Here's a list of colours and the words and concepts I associate with each one:

White - cold, pure, virginal, surrender, cowardice

Black - evil, secret, death, mourning

Red - hot, passionate, off, stop

Green - go, on, sustainable, environment, naive, jealousy

Blue - cold, sad, male, pornographic

Grey - old, drab

Brown - industrial, derelict

Pink - female, healthy

Yellow - cowardice

Purple, royal, regal

I wonder if other cultures have different interpretations.
