Color Conversion

These methods are all about converting colours from one format to another. Think converting a hex code to RGB, so you can use your client's brand colours in an expression in the project, or converting a value to HSL so you can adjust the lightness or saturation procedurally.

Methods

rgbToHsl()

rgbToHsl(rgbaArray)

Description

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.

Parameters

Returns

HSLA Array (4-dimensional)

Example:

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

hslToRgb()

hslToRgb(hslaArray)

Description

Converts a color in HSLA space to RGBA space.

This conversion is the opposite of the conversion performed by the rgbToHsl() method.

Parameters

Returns

RGBA Array (4-dimensional)

hexToRgb()

hexToRgb(hexString)

Description

Converts a color in hex triplet space to RGB space, or in hex quartet space to RGBA space.

For hex triplets, the alpha channel defaults to 1.0.

Parameters

Returns

Array (4-dimensional)

Examples

Any of the following will return [1.0, 0.0, 1.0, 1.0]:

• hexToRgb("FF00FF")
• hexToRgb("#FF00FF")
• hexToRgb("0xFF00FF")
• hexToRgb("0XFF00FFFF")
  • Note: This inputs an 8-digit hex quartet; the last two digits set alpha channel to 1.0.
