const colorTransitions = require('color-transitions');
colorTransitions('blue', 'red', color => {

});API
colorTransitions(color1, color2, options, cb)
color1, color2
Same as the color setter.
options
duration
Type: number
Default: 1000
The transition duration option specifies the number of seconds or milliseconds a transition animation should take to complete.
timing
Type: string or function
Default: 'linear'
The transition timing function option is used to describe how the intermediate values of the color being affected by a transition effect are calculated. This in essence lets you establish an acceleration curve, so that the speed of the transition can vary over its duration.
If this is string, the function would be from eases.
threshold
Type: number
Default: 60
Maximum number of callbacks that can occur in one second.
iterations
Type: number or boolean
Default: 1
How many transitions between two colors. Specify true to make it infinite.
cb
Type: function
Callback function. If return false, stop immediately.
cb(color, delta, iteration)
color
Type: array
RGB array
delta
Type: number
How much time has passed since last callback in milliseconds.
iteration
Type: number
Which iteration. Counting from 1.
done
Type: boolean
Is the transition done?
