Term entry
Color Fastness
The resistance of a fabric's colour to fading or bleeding,rated on a 1-5 grey scale (ISO 105, AATCC, JIS standards), with the $70B+ TIC market driving global testing. Testing costs $5-200 (₹455-18,200) per panel, and color-related quality failures account for 15-20% of garment rejections in global trade.

What is Color Fastness?
Colour fastness (or colourfastness) measures how well a fabric retains its colour under various conditions,one of the most critical quality parameters in global fashion, with the Testing, Inspection, and Certification (TIC) market exceeding $70 billion and growing at 5-6% CAGR. Poor colour fastness leads to fading, bleeding, staining, and customer complaints, with color-related quality failures accounting for 15-20% of garment rejections globally.
Types of colour fastness tests (with global standards):
- Wash fastness: ISO 105 C06 (international), AATCC 61 (USA), JIS L 0844 (Japan),resistance to colour change during washing
- Light fastness: ISO 105 B02 (international), AATCC 16 (USA), JIS L 0842 (Japan),resistance to UV/sunlight fading
- Rubbing fastness (crocking): ISO 105 X12, AATCC 8, JIS L 0849,dry and wet colour transfer from rubbing
- Perspiration fastness: ISO 105 E04, AATCC 15, JIS L 0848,resistance to acid and alkaline sweat
- Water fastness: ISO 105 E01, AATCC 107,resistance to water exposure
Rating scale (1–5 grey scale):
- 5: Excellent,no change (premium/luxury standard)
- 4: Good,slight change (commercial standard)
- 3: Fair,noticeable change (minimum acceptable for most markets)
- 2: Poor,considerable change (below standard,reject)
- 1: Very poor,extensive change (unacceptable,reject)
Acceptable standards by market:
- USA (AATCC): Wash fastness 4+, rubbing 3-4 dry / 2-3 wet, light fastness 4+ for summer
- EU (ISO): Wash fastness 4+, strict REACH chemical compliance, light fastness 4+ outdoor
- Japan (JIS): Stringent standards,wash fastness 4-5, rubbing 3-4, perspiration 4+
- Children's wear (all markets): 4-5 across all tests (strictest requirements)
- Premium/luxury: 4-5 across all tests, zero tolerance for bleeding
Major testing organizations:
- SGS (Switzerland, $7.6B revenue): Global leader in textile testing
- Intertek (UK): Full textile testing with 1,000+ labs worldwide
- Bureau Veritas (France): International testing and certification
- TUV (Germany): Technical testing with international accreditation
Why this matters for fashion entrepreneurs.
Colour fastness failures are one of the top reasons for customer complaints and returns globally,color-related quality issues account for 15-20% of garment rejections in international trade. A single batch of bleeding or fading garments can damage your brand reputation significantly.
Investment by brand stage (USD + ₹):
- Startup (1-5 styles): Budget $100-500 (₹9,100-45,500) per season for testing. Request reports from fabric supplier, supplement with independent lab testing on high-risk colors
- Growing brand (10-30 styles): Budget $500-2,000 (₹45,500-182,000) per season. Test every fabric lot. Negotiate annual contracts with SGS/Intertek for 20-30% discounts
- Established brand (50+ styles): Budget $2,000-8,000 (₹182,000-728,000) per season. In-house crocking testers ($500-2,000, ₹45,500-182,000) for rapid screening before lab submission
Preventive steps:
- Test before bulk: Independent lab testing ($5-200/panel, ₹455-18,200) is essential,never rely solely on supplier claims
- Specify standards in POs: Include minimum fastness ratings (wash 4+, rubbing 3-4 dry, light 4+ for summer) in purchase specifications
- Test after garment washing: Washing processes alter fastness,test finished product, not just fabric
- Educate customers: Accurate care labels prevent avoidable colour issues and reduce returns
Highest-risk categories:
- Dark colours (navy, black, red) on light fabrics,bleeding risk (reactive dyes fix better than direct dyes)
- Natural dyes,inherently lower wash fastness (2-3 vs. 4-5 for synthetic)
- Bright/neon colours,lower light fastness
- Pigment-printed fabrics,lower rubbing fastness (especially wet crocking)

Frequently asked.
Colour fastness measures how well a fabric retains its colour under conditions like washing, light exposure, rubbing, and perspiration. It's critically important because color-related quality failures account for 15-20% of garment rejections in global trade. Testing follows ISO 105 (international), AATCC (USA), or JIS (Japan) standards, rated on a 1-5 grey scale where 5 is excellent and 1 is very poor. The TIC (Testing, Inspection, Certification) market exceeds $70 billion, with SGS ($7.6B revenue), Intertek, and Bureau Veritas as leading testing providers.
Standards vary by market: USA (AATCC) requires wash fastness 4+, rubbing 3-4 dry / 2-3 wet, light fastness 4+ for summer wear. EU (ISO 105) requires wash 4+, strict REACH compliance, light 4+ for outdoor. Japan (JIS) demands stringent wash 4-5, rubbing 4+ for premium products. Children's wear requires 4-5 across all tests in all markets (strictest requirements). Premium/luxury brands specify 4-5 across all tests with zero bleeding tolerance. Always specify requirements in writing in your purchase orders,"standard quality" means different things to different suppliers.
Costs vary by region: USA $50-200 (₹4,550-18,200) per full panel using AATCC standards. UK/Europe £30-150 ($38-192, ₹3,458-17,472) per panel with ISO 105 compliance. Japan ¥5,000-30,000 ($33-200, ₹3,003-18,200) per panel using JIS standards. India ₹3,000-8,000 ($33-88) at labs like ATIRA, BTRA, SITRA. Asia (China/Bangladesh) $5-50 (₹455-4,550),most cost-effective. Rush testing (1-2 days) adds 50-100% surcharge. Annual contracts with SGS, Intertek, or Bureau Veritas save 20-30%. Testing costs are negligible vs. rejection costs of $1,000-5,000+ (₹91,000-455,000+) per failed production lot.
