I considered the Color Index my bible, so I’m always on the lookout for web based color generators when I don’t have my prized book handy. Coolors, a web site and app is a super easy to use color generator. It starts off by giving you five colors that work together and if you don’t like any of them, keep hitting the space bar to load up more colors. If you find a color or colors you like, you can lock them in.
Coolors also makes it easy to adjust the hue and saturation of a color to perfect it and you can switch back and forth between RGB and CMYK to perfect the color’s settings. You also get the color code to use for the web. They also have popular palettes to browse if are looking for some inspiration. A little warning, the site can be rather addicting.
