Overview

A color represents the color, and sometimes opacity (alpha) of an object.

When calling a method that expects a Color object, a 3-element Array (red-green-blue) or 4-element Array (red-green-blue-alpha) can be passed instead, as a convenience shortcut. For example,

node.color = [0.2, 0.3, 0.4]

is the same as

color = MG::Color.new
color.red = 0.2
color.green = 0.3
color.blue = 0.4
node.color = color

Alternatively, a Symbol corresponding to a basic color name can be provided. For example,

node.color = :red

is the same as

color = MG::Color.new
color.red = 1.0
color.green = color.blue = 0
node.color = color

Currently, the following symbols are supported: :white, :black, :red, :green and :blue.
