So not assuming anyone is some kind of colour pro, I still want to ask if anybody knows of a purple that would look black in cloudy weather for example and purple in the sun. What I mean is that it's extremely dark but not so dark that it appears black all the time. And if not, then is there a certain type of finish that give off that effect like a pearlescent finish or anything of the sort? I just really want that effect on my wire spokes for the fixie I'm building. Thanks for your help in advance! Sorry if I'm not posting in the right place, I'm new here...
