color operation

Syntax

color(hexValue)

color(red, green, blue)

color(red, green, blue, opacity)

Parameters

hexValue (string)
Color to set, in the format "#rrggbb" or "#rrggbboo" (hex).
red, green, blue, opacity (float)
Color to set in red, green, blue, opacity components (range is 0.0 to 1.0).

Description

The color operation sets the color of the current shape's material. Input parameter values for red, green, blue, or opacity that are outside the range [0,1] are clamped to [0,1].
In CGA, colors are always in (non-linear) sRGB.

Note: this command has the same effect as set(material.color.{r|g|b}, val), it is a shortcut for convenience.

Examples

Three ways to set a shape's color

   extrude(20)
   split(x) { 
      2 : color("#ff0000") X |
      2 : color(1, 0, 0) X |
      2 : set(material.color.r, 1.0) 
          set(material.color.g, 0) 
          set(material.color.b, 0) X
