Poline
What It Does
The Poline node generates a smooth color palette between multiple anchor colors using the Poline algorithm. It creates sophisticated color progressions by interpolating through 3D color space with customizable distribution functions. Read more about Poline.

How to Use It
Drag the Poline node into your graph.
Connect at least two colors to the "Anchor Colors" input. (You can create an array of colors using the Arrify node).
Set "Num Points" to control how many colors are in the final palette (default: 4).
Optionally customize the position functions and other parameters. Read more about these parameters.
The output will be an array of colors creating a smooth palette between the anchor colors. So if the input is two colors and the "Num Points" is 4, the output will be an array of six colors.
Tips
Different position functions create different distribution patterns (sinusoidal is the default).
More anchor colors create more complex, multi-dimensional palettes.
Try inverting lightness to create interesting contrast variations.
