Morphology

lightfast = light + fast (semi-transparent) = light + fast

Components are identifiable ('light' + 'fast') but 'fast' here means 'firmly fixed/resistant', which may be confused with 'quick', so learners may not reliably infer 'resistant to fading'.

Etymology

The word lightfast comes from the parts light and fast, where fast means 'firm' or 'held', like in 'steadfast' or 'hold fast'. So lightfast describes colors or dyes that stay true in light and do not fade.
