Detailed Description

An RGBA color with floating-point components.

Each channel is in the range [0.0, 1.0], where 0.0 is none and 1.0 is full intensity. The alpha channel (a) controls opacity: 1.0 is fully opaque, 0.0 is fully transparent.

Colors are used to describe vertex colors, face colors, light colors, background colors, and more throughout the engine.

Constructing colors

Color red(1.0f, 0.0f, 0.0f);          // opaque red
Color half_blue(0.0f, 0.0f, 0.5f);    // semi-dark blue
Color transparent_green(0.0f, 1.0f, 0.0f, 0.3f); // green, 30% opaque
