/* Utility class for manpulating RGBA colors.
 *
 * SFML::Color is a simple color class composed of 4 components:
 *
 *   - Red
 *   - Green
 *   - Blue
 *   - Alpha (opacity)
 *
 * Each component is a public member, an unsigned integer in the range [0, 255]. Thus, colors can be constructed and manipulated very easily:
 *
 *   c1 = SFML::Color.new(255, 0, 0)	# red
 *   c1.red = 0				# make it black
 *   c1.blue = 128			# make it dark blue
 *
 * The fourth component of colors, named "alpha", represents the opacity of the color. A color with an alpha value of 
 * 255 will be fully opaque, while an alpha value of 0 will make a color fully transparent, whatever the value of the 
 * other components.
 * 
 * The most common colors are already defined as class constants:
 *
 * black   = SFML::Color::Black
 * white   = SFML::Color::White
 * red     = SFML::Color::Red
 * green   = SFML::Color::Green
 * blue    = SFML::Color::Blue
 * yellow  = SFML::Color::Yellow
 * magenta = SFML::Color::Magenta
 * cyan    = SFML::Color::Cyan
 *
 * Colors can also be added and modulated (multiplied) using the overloaded operators + and *.
