Color Conversion¶
These methods are all around 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¶
| Parameter | Type | Description |
|---|---|---|
rgbaArray |
Array of numbers (4-dimensional) | RGBA values, in the range [0.0..1.0] |
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¶
| Parameter | Type | Description |
|---|---|---|
hslaArray |
Array of numbers (4-dimensional) | HSLA values, in the range [0.0..1.0] |
Returns¶
RGBA Array (4-dimensional)
hexToRgb()¶
hexToRgb(hexString)
Note
This functionality was added in After Effects 16.0.
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¶
|
Parameter |
Type |
Description |
|---|---|---|
|
|
String |
Hex triplet (6 digits, no alpha channel) or quartet (8 digits, includes alpha channel) containing only numerals or characters A–F. |
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.
