When working on a web design project, inspiration can come from many sources. Estabilshing a color palette is often where I begin and a great resource is COLOURlovers
COLOURlovers is a color and design community that offers a wealth of resources for picking colors and staying on top of color trends and is great for kick starting inspiration.
Kuler from Adobe http://kuler.adobe.com/ is another great site for playing with color palettes.
