Like taste and smell, color is a sense that is processed by our brains in multiple dimensions. Yet traditional methods of choosing colors on computers are limited to obscure sliders and flattened two-dimensional viewers. With ColoRotate, you can work with colors in 3D, in real time, and in a way that matches how our minds process color.

ColoRotate has an intuitive interface that eliminates the need to memorize or jot down color combinations or numbers. Indeed, you can traverse across an open three-dimensional color space and choose (or design) the color palette that fits your needs.
