Class representing a color with four floats.
The color values for red, green, blue and alpha are each stored in a 32 bit floating point variable. So all four values may be between 0.0f and 1.0f. Another, faster way to define colors is using the class SColor, which stores the color values in a single 32 bit integer.

inline |
Constructs a color from up to four color values: red, green, blue, and alpha.
r | Red color component. Should be a value between 0.0f meaning no red and 1.0f, meaning full red. |
g | Green color component. Should be a value between 0.0f meaning no green and 1.0f, meaning full green. |
b | Blue color component. Should be a value between 0.0f meaning no blue and 1.0f, meaning full blue. |
a | Alpha color component of the color. The alpha component defines how transparent a color should be. Has to be a value between 0.0f and 1.0f, 1.0f means not transparent (opaque), 0.0f means fully transparent. |
