Nodes

Color Grayscale

Converts a color to grayscale, preserving white channels. Also outputs the overall lightness as a number.

Inputs: A color to convert.

Name	Type	Range	Default
Color	Color	color	[255, 255, 255, 255, 255, 255]

Outputs: Grayscale color and a lightness value (0 to 1).

Name	Type	Range
Color	Color	color
Lightness	Number	any

Combine Color

Builds a color from separate channel values. Use when you need individual control over each color channel.

Inputs: Individual values for Red, Green, Blue, White, Amber, and UV channels (0-255).

Name	Type	Range
Red	Number	0-255
Green	Number	0-255
Blue	Number	0-255
White	Number	0-255
Amber	Number	0-255
UV	Number	0-255

Outputs: The combined color.

Name	Type	Range
Color	Color	color

Builds a smooth looping color ramp from four control vectors, one component per RGB channel: Bias sets the average color, Amplitude the contrast, Frequency how many times each channel cycles, and Phase where each channel starts. Sweep T with time or position for gradients that never band.

Inputs: T (the position along the ramp, usually 0-1) plus the bias, amplitude, frequency, and phase vectors.

Name	Type	Range	Default
T	Number	0-1	0
Bias	Vector	vec:0-1	[0.5, 0.5, 0.5]
Amplitude	Vector	vec:0-1	[0.5, 0.5, 0.5]
Frequency	Vector	vec	[1, 1, 1]
Phase	Vector	vec:0-1	[0, 0.33, 0.67]

Outputs: The sampled color, with each channel clamped to 0-255.

Name	Type	Range
Color	Color	color

HSL to RGB

Creates colors using Hue, Saturation, and Lightness. Easier for creating color cycles and rainbow effects.

Inputs: Hue (cycles through the rainbow every 1.0; any value works, it is wrapped into 0-1 internally so a rising time input keeps cycling), Saturation (0=gray, 1=vivid), Lightness (0=black, 0.5=full color, 1=white).

Name	Type	Range
Hue	Number	any (wraps every 1)
Saturation	Number	0-1
Lightness	Number	0-1

Outputs: Red, Green, Blue values (0-255).

Name	Type	Range
Red	Number	0-255
Green	Number	0-255
Blue	Number	0-255

RGBW to HSL

Extracts Hue, Saturation, and Lightness from a color. Useful for manipulating colors in HSL space.

Inputs: A color to analyze. 'Merge White' blends the white channel into RGB before conversion.

Name	Type	Range	Default
Color	Color	color	[0, 0, 0, 0, 0, 0]
Merge White	Boolean	bool	false

Outputs: Hue (0-1, rainbow position), Saturation (0-1, color intensity), Lightness (0-1, brightness).

Name	Type	Range
Hue	Number	0-1
Saturation	Number	0-1
Lightness	Number	0-1

Split Color

Separates a color into its individual channels. Use to manipulate or read specific color components.

Inputs: A color to split.

Name	Type	Range	Default
Color	Color	color	[0, 0, 0, 0, 0, 0]

Outputs: Separate Red, Green, Blue, White, Amber, and UV values (0-255).

Name	Type	Range
Red	Number	0-255
Green	Number	0-255
Blue	Number	0-255
White	Number	0-255
Amber	Number	0-255
UV	Number	0-255
