Swatchy is a mobile app for iPhone/iPad to help you quickly define the color you want.
Create color swatches on-the-fly, email them, share them with other Swatchy users, or save them to your photos. Create swatches by using Swatchys easy-to-use picker; or sample from photos youve taken; or choose from a growing library of shared swatches (which are created by you and other users!).
If you deal with color numbers on a regular basis, Swatchy is an easy reference to get HEX, RGB or HSV info from any color. You can email this info; save to your clipboard; or micro-adjust any color measurement as you wish.
