Most people are just like me, always stick to gray, black  color to stay low profile, someone told me if i should change some bright color to make a different mood and style.

Good idea, but i found my choice is so limited, i dislike purple, they are not looking good on me, and green is common choice, what else, yellow ?

Basically, gray or black color as the main background color is no mistake in most times, but if too many, it’s been so plain and bored, so what do you think the bright color choice ?
