As always I am researching social networking sites that might have value to me. Well, one of my favorite social netorking sites that I use all the time with my designs is ColourLovers. This site allows members of the community to upload palettes, colors, and patterns. To the left you can see a pattern I thought was nice. Check out how you can score that pattern and discuss it. It even ranks them. One of the very cool aspects of this site is the ability to actually download the palettes.
This site can be useful if you are painting a room. Building a website or even painting a picture. It is just a great way to share color finds and exchange your ideas with others that are pationate about colors and patterns.
I am actually looking for colors on ColourLovers myself for our downstairs bathroom.
