Color change unless done pretty much completely always seems cheap to me. It seems to degrade the car in some ways.

Can also involve a lot more work to do it. Based partially on the above I try to stay with the same color. That is just me though.

I really do not mind what anyone else does in this regard at the same time. For example I have an 84 with serious paint flaws that needs redone. Some like the color and others dislike it. I am not in love with it myself. Still I will repaint it the same color and hope the freshness of the new paint changes my opinion of it.
