API
For any method the input arguments can be an object (r: 50, g: 100, b: 0}
or a set of integers 50, 100, 0
. You have aliases in both snake_case (hex_to_hsl
) or rgb2Hex
, hsv2Rgb
form.
colorsys.parseCss(color: string)
will parse a color string in an object with the same keys.colorsys.stringify(color: Object)
will output a valid css string.colorsys.rgb_to_hsl({ r: 255, g: 255, b: 255 }) => { h: 0 , s: 0 , l: 100 }
colorsys.rgb_to_hsv({ r: 255, g: 255, b: 255 }) => { h: 0 , s: 0 , v: 100 }
Try with any combination. Look at the source to double check!
