解説 رنگ‌ثابت in your Level:

At the A1 level, you only need to know that 'rang' means color and 'sābet' means fixed or stable. Think of this word as a 'label' you see in shops. When you go shopping for a T-shirt or a simple bracelet in Iran, you can point to it and ask: 'In rang-sābet ast?' (Is this colorfast?). It is a very useful word for basic survival and shopping. You don't need to worry about complex grammar yet. Just remember it as one single word that means 'the color stays.' You might see it on price tags or hear a shopkeeper say it to convince you to buy something. It's like saying 'good quality' but specifically for the color. If you buy a cheap shirt and the color washes away, it was NOT 'rang-sābet.' Learning this word early helps you avoid buying things that will be ruined in the first wash.

رنگ‌ثابت 30秒で

Means 'colorfast' or 'non-fading'.
Used for textiles, jewelry, and hair dye.
A key indicator of high quality in Persian markets.
A compound of 'rang' (color) and 'sābet' (fixed).

The term رنگ‌ثابت (pronounced 'rang-sābet') is a compound adjective in Persian that translates literally to 'fixed color' or 'stable color.' In practical, everyday English, it is most accurately rendered as 'colorfast' or 'non-fading.' This word is a cornerstone of Persian commerce, particularly in industries where the longevity of visual appearance is paramount. When a Persian speaker describes an item as rang-sābet, they are offering a guarantee of quality, asserting that the item will not bleed, fade, or lose its vibrancy after being washed, exposed to sunlight, or subjected to regular wear and tear. This is not just a technical descriptor; it is a mark of reliability in a market where traditionally dyed textiles and handcrafted goods are highly valued.

Textile and Fashion Context: In the world of Persian fashion and home decor, particularly regarding the famous Iranian carpets (qali) and intricate fabrics like 'Termeh' or 'Ghalamkar,' this word is essential. A carpet that is not رنگ‌ثابت is considered a major defect, as the colors might 'run' (rang dādan) during the first wash, ruining the intricate patterns. When shopping in a traditional bazaar in Isfahan or Tehran, you will frequently hear customers ask, 'Āyā in pārche rang-sābet ast?' (Is this fabric colorfast?).
Jewelry and Accessories: Interestingly, the term has expanded beyond fabrics. In the modern Iranian market, it is heavily used for 'badalijāt' (costume jewelry). High-quality gold-plated or stainless steel jewelry is marketed as بدلیجات رنگ‌ثابت, meaning the golden or silver finish will not turn black or peel off when in contact with water or sweat.

'من فقط لباس‌هایی می‌خرم که رنگ‌ثابت باشند تا بعد از شستن خراب نشوند.'
— I only buy clothes that are colorfast so they don't get ruined after washing.

The word is composed of two parts: رنگ (rang), meaning 'color,' and ثابت (sābet), an Arabic-derived word meaning 'fixed,' 'stable,' or 'constant.' Together, they create a concept of permanence. In a deeper cultural sense, Iranians value things that 'māndegār' (last long), and rang-sābet is a specific type of durability. It reflects a culture that historically relied on natural dyes extracted from madder root, pomegranate skin, and indigo—dyes that, when applied correctly with a mordant, became legendary for their 'rang-sābet' quality, lasting for centuries in museum-grade carpets.

Furthermore, the term appears in technical manuals for printing, automotive paints, and even hair dyes. If a hair dye is described as rang-sābet, it implies a permanent dye rather than a semi-permanent or temporary one. In the digital age, graphic designers might even use it to discuss 'color profiles' that remain consistent across different screens, though this is a more modern, borrowed application of the concept.

Using رنگ‌ثابت correctly in a sentence requires an understanding of Persian adjective placement. Typically, it follows the noun it modifies, connected by the 'Ezafe' (the short 'e' sound). For example, 'pārche-ye rang-sābet' (colorfast fabric). However, it can also function as a predicate adjective, as in 'In pārche rang-sābet ast' (This fabric is colorfast).

Attributive Usage (N + e + Adjective): This is the most common way to describe a product.
Example: تی‌شرتِ رنگ‌ثابت (Colorfast T-shirt).
Example: رنگ‌هایِ ثابتِ گیاهی (Fixed vegetable dyes).
Predicative Usage (Subject + Adjective + Verb): Used to make a claim about an object.
Example: این بدلیجات رنگ‌ثابت هستند؟ (Is this costume jewelry colorfast?).
Note how the plural verb 'hastand' matches the plural subject 'badalijāt'.

'فروشنده تضمین کرد که تمامِ محصولاتش رنگ‌ثابت هستند.'
— The seller guaranteed that all his products are colorfast.

In more formal or industrial contexts, you might see the term used in compound nouns or technical descriptions. For instance, in a textile factory manual, you might find 'āzmāyesh-e rang-sābeti' (colorfastness test), where the suffix '-i' is added to turn the adjective into an abstract noun. This is a common pattern in Persian word formation.

When comparing products, you might use 'rang-sābet-tar' (more colorfast), though this is less common than simply saying 'quality is better.' A more natural way to express high colorfastness is 'kamelan rang-sābet' (completely colorfast). In contrast, if something fades, we use the verb 'rang bākhtan' (to lose color) or 'rang paridan' (to fade/pale), but 'rang-sābet' remains the gold standard for the positive attribute.

To truly master رنگ‌ثابت, you must listen for it in the specific environments where quality and durability are discussed. It is a 'buying and selling' word, deeply embedded in the Persian mercantile psyche. If you walk through the Grand Bazaar of Tehran, particularly the sections selling linens, curtains, or towels, this word will be part of the ambient noise.

In the Bazaar (Traditional Markets): Sellers use it as a persuasive tool. You will hear: 'Khānum, in jens-esh ali-ye, rang-sābet-e!' (Ma'am, the material is excellent, it's colorfast!). It acts as a shorthand for 'high quality' and 'washable.'
On Television and Social Media Ads: Instagram shops in Iran (which are massive) often put '#رنگ_ثابت' in their captions. TV commercials for laundry detergents like 'Persil' or 'Omo' often mention how their product protects 'pārche-hā-ye rang-sābet' (colorfast fabrics) while cleaning.

'آیا این گوشواره‌ها واقعاً رنگ‌ثابت هستند یا بعد از مدتی سیاه می‌شوند؟'
— Are these earrings really colorfast, or will they turn black after a while?

You will also hear this word in beauty salons. When a client asks for a hair color that won't wash out quickly, the stylist might recommend a 'rang-e dā'emi' (permanent color) and explain its rang-sābet properties. Similarly, in the automotive industry, when discussing a high-quality paint job or ceramic coating, a specialist might emphasize that the finish is rang-sābet against UV rays and harsh weather.

Finally, in the context of household chores, mothers often warn their children: 'In lebās-o bā lebās-hā-ye sefid nandāz, rang-sābet nist!' (Don't throw this shirt in with the whites; it's not colorfast!). This warning is a common part of domestic life in Iran, where sorting laundry by color stability is a standard practice to prevent the dreaded 'rang dādan' (color bleeding).

For English speakers learning Persian, the most common mistakes with رنگ‌ثابت usually involve confusion with similar-sounding words or incorrect grammatical structures. Because 'rang' (color) is such a versatile word, it's easy to mix up its various compounds.

Mistake 1: Confusing with 'Rangin': Learners often use 'rangin' (colorful) when they mean 'rang-sābet' (colorfast). While a 'rangin-kamān' (rainbow) is beautiful, it isn't 'fixed.' If you tell a seller you want a 'pārche-ye rangin,' you are asking for colorful fabric, not necessarily one that won't fade.
Mistake 2: Missing the 'Half-Space' (Nim-Fāsele): In writing, rang-sābet is a compound. It should ideally be written with a half-space (رنگ‌ثابت) rather than a full space (رنگ ثابت) or no space (رنگثابت). While modern texting often ignores this, in formal writing or exams, the half-space is crucial for showing it's a single lexical unit.

'Incorrect: این لباس رنگِ ثابت است. (Using Ezafe where it doesn't belong)'
— Correct: این لباس رنگ‌ثابت است.

Another mistake is using rang-sābet to describe a person's personality. In English, we might say someone has 'true colors' or is 'steady,' but in Persian, rang-sābet is almost exclusively reserved for physical objects and materials. To describe a person's consistency, you would use 'sābet-ghadam' (firm-footed/steadfast) or 'yek-rang' (one-colored/sincere).

Lastly, avoid the literal translation of 'colorfast' as 'rang-e tond' (fast/quick color). In Persian, 'rang-e tond' means a sharp or bright color, often one that is garish or overwhelming. If you ask for a 'fast color' using the literal word for speed, you will likely be shown neon pink or bright orange instead of a durable fabric!

While رنگ‌ثابت is the most common term for colorfastness, Persian offers several other words that touch upon durability, color quality, and permanence. Understanding these nuances will help you sound more like a native speaker and better understand product descriptions.

با‌دوام (Bā-davām): Meaning 'durable' or 'long-lasting' in a general sense. While rang-sābet specifically refers to the color, 'bā-davām' refers to the physical integrity of the item. A pair of boots might be 'bā-davām' even if the color scuffs off.
ماندگار (Māndegār): Meaning 'everlasting' or 'memorable.' This is often used for perfumes (long-lasting scent) or art. While you wouldn't usually call a T-shirt 'māndegār,' you might call the natural dyes of a 100-year-old carpet 'māndegār.'

'این رنگ مو دائمی است و با شستشو پاک نمی‌شود.'
— This hair color is permanent and doesn't wash out.

In the context of jewelry, you might encounter 'zed-e hassāsiat' (hypoallergenic). Often, rang-sābet and 'zed-e hassāsiat' are paired together in advertisements for stainless steel jewelry. Another related term is 'zed-e āb' (waterproof), though this refers to the mechanism (like a watch) rather than the surface color.

If you are looking for the opposite of rang-sābet, you might use 'rang-paride' (faded/pale) or the phrase 'rang midahad' (it gives color/it bleeds). For example, 'In jin rang midahad' (These jeans bleed color). Understanding the verb 'rang dādan' is the best way to explain why you are specifically looking for something that is rang-sābet.

豆知識

In ancient Persian carpet making, colorfastness was achieved using 'dandāne' (mordants) like alum or iron vitriol. A carpet that wasn't 'rang-sābet' could lose half its value instantly.

ヒント

Check the Label

When buying jewelry in Iran, look for the 'رنگ ثابت' stamp or tag to ensure it won't turn black.

Compound Power

Remember that compound adjectives like this don't change for plural nouns. 'Lebās-hā rang-sābet hastand'.

Bazaar Trust

Sellers often say 'be sharte rang-sābet' (on the condition of being colorfast) to build trust.

Synonym Alert

In very formal textile reports, you might see 'ثبات رنگ' (sobāt-e rang) instead of the adjective.

Keyboard Tip

Use 'Shift + Space' on most Persian keyboards to type the half-space in رنگ‌ثابت.

Testing

To test if something is 'rang-sābet', rub a damp white cloth on an inconspicuous area.

Hair Dye

Ask for 'rang-e dā'emi' (permanent color) if you want a 'rang-sābet' result for your hair.

Material Matters

Usually, 'steel' (estil) jewelry in Iran is marketed as 'rang-sābet'.

Ancient Tech

Persian carpets are 'rang-sābet' because of natural mordants like pomegranate skin.

Intonation

チャレンジ

Go to an online Iranian shop (like Digikala) and search for 'rang-sābet'. See how many different types of products use this description.

語源

A compound of the Middle Persian 'rang' (color/hue) and the Arabic 'thābit' (ثابت), meaning firm, established, or unchanging. The merger of Persian and Arabic vocabulary is typical of post-Islamic Persian.

元の意味： Literally 'unchanging hue.'

Indo-European (Persian) + Afro-Asiatic (Arabic).

文化的な背景

No specific sensitivities, but be aware that 'rang-sābet' in jewelry is often a relative term; even 'fixed' colors can eventually wear off after years of heavy use.

Equivalent to 'colorfast' in textiles or 'permanent' in dyes. English speakers might use 'tarnish-resistant' for jewelry, which is covered by 'rang-sābet' in Persian.
