I just found my new favorite site - and I have to be careful because I could easily while away whole days of my life there. It's called COLOURLovers.com. From the site's About page: COLOURLovers is an international community of designers and artists of all kinds who visit the site to get color inspiration, ideas and feedback for both their professional and personal projects. COLOURLovers' loyal members create colors, palettes, and patterns to nurture their ongoing love affair with color.
You can create color combinations in palettes or apply them to pre-made patterns. The 2 examples above are ones I made doing the latter. The one on top I named "Attentive" and the bottom one is called "Tupperware Party 1976."
