In order to get inspired on colors and color-oriented design resources, there are several popular websites that are focused totally on colors, like Kuler from Adobe.

Colrd is another one where you can find high quality color palettes, gradients or patterns and also share your creativity with others.

With a simplistic interface that highlights the resources, it is possible to filter items by colors, popularity and even hue, luminance, etc.

P.S. Colrd has also created and sharing several open source color pickers.
