Colourfastness Is an Affinity Edge
The claim
Colourfastness is set by whether dye-fibre affinity exceeds the wash liquor's stripping power, not by initial shade depth.
01The mechanism
Dye partitions between fibre and liquor; when the partition falls below a threshold, the shade migrates regardless of how much was applied.
02Predictions
- P1Fastness should track the affinity ratio.
- P2Deeper shades should not improve fastness.
03Refutation
Fastness tracking shade depth would remove the partition term.
