Morphology
The meaning 'to maintain or prevent fading of original colors' is directly and compositionally derived from 'preserve' (to keep unchanged) combined with 'colors' (visual attributes). This verb + noun collocation follows a transparent, cross-linguistically common pattern, so a B1 learner who knows both words will readily understand the MWE.
Etymology
Preserve colors comes from the simple image of covering cloth or paintings so their bright colors stay safe from sun and rough washing. So, to preserve colors means to protect the original look so the colors do not 'fade'.
