RgbColor class

A color in the sRGB color space.

The sRGB color space contains channels for red, green, and blue.

RgbColor stores RGB values as nums privately in order to avoid a loss of precision when converting between color spaces, but has getters set for red, green, and blue that return the rounded int values. The precise values can returned as a list with the toPreciseList() method.
