rgbToHsl(rgbaArray)

Return type: Array [4].

Argument type: rgbaArray is an Array [4].

Converts a color in RGBA space to HSLA space. The input is an Array of normalized red, green, blue, and alpha channel values, all in the range of 0.0 to 1.0. The resulting value is an Array of hue, saturation, lightness, and alpha channel values, also in the range of 0.0 to 1.0. Example:

  rgbToHsl.effect("Change Color")("Color To Change")

hslToRgb(hslaArray)

Return type: Array [4].

Argument type: hslaArray is an Array [4].

Converts a color in HSLA space to RGBA space. This is the opposite of rgbToHsl.
