Prismatic Illustrations
The Prismatic model introduces a simple transform of the RGB color cube into a light/dark dimension and a 2D hue. The hue is a normalized (barycentric)triangle with pure red, green, and blue at the vertices, often called the Maxwell Color Triangle. Each cross section of the space is the same barycentric triangle, and the light/dark dimension runs zero to one for each hue so the whole color volume takes the form of a prism.

Input/Output
The Prismatic space is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --prismatic:
color(--prismatic l r g b / a) // Color function
The string representation of the color object and the default string output use the color(--prismatic l r g b / a) form.
>>> Color("prismatic", [1, 1, 0, 0])
color(--prismatic 1 1 0 0 / 1)
>>> Color("prismatic", [1, 0.60714, 0.39286, 0], 1).to_string()
'color(--prismatic 1 0.60714 0.39286 0)'
