Which colours last longest in the wash
Short answer: Mid dark and muted colours last longest. Black, bright red and deep navy lose visibly first, while white can be restored.
Why some colours lose first
The more dye a colour needs, the more it has to lose before it shows. Black and bright colours are therefore the most exposed. Muted tones contain less dye and change more slowly.
White is a special case
White cannot fade, but it turns grey or yellow from soil and skin oils. On the other hand white can be restored with oxygen bleach, which coloured clothes cannot. See bamboo underwear for men.
How to extend the colour's life
Wash at thirty degrees inside out, dose for your water hardness, skip the softener and dry in shade. Those four habits matter more than the colour itself. See bamboo clothing for women and bamboo clothing for men.

Washed cool and dried in shade, most colours last a few hundred washes without clear loss.

No. Dye type and washing habits matter more than the fibre.
