Color Nodes

Build, split, and convert colors, including HSL conversion and a cosine palette.

This category contains 6 nodes.

Nodes

Color Grayscale

Converts a color to grayscale and keeps its white channels. It 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, so you control each channel on its own.

Inputs: One value each for the Red, Green, Blue, White, Amber, and UV emitters. Each value is that emitter's share of its full light output, on a 0-255 scale. 255 is the emitter at full, and 128 is half its light. Spectralite calculates the DMX level each fixture needs to put out that much light.

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.

Cosine Palette

Builds a smooth looping color ramp from four control vectors, with one component per RGB channel. Bias sets the average color, and Amplitude sets the contrast. Frequency sets how many times each channel cycles, and Phase sets where each channel starts. Sweep T with time or position for a smooth gradient.

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 the 0-255 scale, where 255 is that emitter at full.

HSL to RGB

Converts Hue, Saturation, and Lightness to Red, Green, and Blue values. Color cycles and rainbow effects are easier to build in HSL than in RGB.

Inputs: Hue cycles through the rainbow every 1.0. Any value works because the node wraps it into 0-1, so a rising time input keeps cycling. Saturation runs from 0 (gray) to 1 (vivid). Lightness runs from 0 (black) through 0.5 (full color) to 1 (white).

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

Outputs: Red, Green, and Blue values. Each value is that emitter's share of its full light output on a 0-255 scale, where 255 is the emitter at full.

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. Use it to adjust a color in HSL terms.

Inputs: The color to analyze. Merge White blends the white channel into RGB before the 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 it to read or change specific channels.

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. Each value is that emitter's share of its full light output on a 0-255 scale, where 255 is the emitter at full.

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
