It certainly is a wonderful world of color but designers can become overwhelmed, and sometimes stuck in a rut, when it comes to selecting colors for design projects. Here are a couple of handy sites for some colorful inspiration:
Color Scheme Designer: Pick and hue, any hue, and see it mono, complement, triad, tetrad, anagogic or accented anagogic.
0 to 255: This simple tool helps web designers find variations of any hex color.
Have fun and always use colors responsibly!
