I originally created ColorSpark as a simple web tool that generates random colors and gradients to help designers discover colors they may not otherwise think to use. This plugin for Sketch follows the same concept, but now allows designers to generate colors directly in the project they are working on.
Accurately produce tints (lighter variants) and shades (darker variants) of a given hex color in 10% increments.
It's best used when you already have a base color palette but would like some complimentary colors for gradients, borders, backgrounds, shadows or other elements. Simple, precise, and open source.
