One of my favorite websites, COLOURlovers is a definite source of inspiration.
Taken from colourlovers' site:
COLOURlovers ™ is a resource that monitors and influences color trends. COLOURlovers gives the people who use color - whether for ad campaigns, product design, or even in architectural specification - a place to check out a world of color, compare color palettes, submit news and comments, and read color related articles and interviews.
The COLOURlovers ™ community is regularly updated with information and examples of the way colors are used in the real world -- along with news articles on color trends and interviews with top creative professionals. (...)
