ColorRGBA defines a color value in the jME library. The color value is made of three components, red, green and blue. A fourth component defines the alpha value (transparent) of the color. Every value is set between [0, 1]. Anything less than 0 will be clamped to 0 and anything greater than 1 will be clamped to 1.

Note: If you would like to “convert” an ordinary RGB value (0-255) to the format used here (0-1), simply multiply it with: 1/255.

ColorRGBA defines a few static color values for ease of use. That is, rather than:

ColorRGBA red = new ColorRGBA(1,0,0,1);
object.setSomeColor(red);

you can simply say:

object.setSomeColor(ColorRGBA.red)

ColorRGBA will also handle interpolation between two colors. Given a second color and a value between 0 and 1, a the owning ColorRGBA object will have its color values altered to this new interpolated color.
