If you got to this page looking for a simple HSL-RGB converter that returns BYTE components as used by Windows, you may prefer to use the HSL-RGB Converter. |
gColor is designed for fast, accurate colour manipulation.
Each colour component (R,G,B,A) is held as a double in the interval [0,1].
Each component can be set or retrieved as float or double with this interval as well as BYTE or int in the interval [0,255].
Constructors exist to create a colour from the components, as well as from the Hue (pick a colour from the spectrum in the interval [0,1]), a 'NoColor' (useful when a system has a 'default colour'), or a random colour.
Saturation can be set using Perceived Luminance in its calculation (see image).
Brightness is adjustable and some static methods provide Gamma Correction, Exposure and Light Power methods.
The RGBA components can be set or retrieved as HSL or HSV components.
A Colour Spline (for implementing a Colour Bar for gradient fills etc.) can be interpolated:
