 * Leverages [Chromajs.set](https://gka.github.io/chroma.js/#color-set) to change the color
 *
 * ## Config Object
 *  * **channel**: 'string' refers to channel of the color. For ex: 'hsl.l' or 'hsl.s' or 'rgb.b'
 *  * **value**: 'string' or 'number'. Can be used to set absolute. For ex: setColorChannel({channel: 'hsl.h', value: 0}). Can be used as relative. For ex: setColorChannel({channel: 'lab.l', value: '*0.5'})
