Abstract: A bitmap may be transformed from one color scheme to another. In one example, the bitmap is used as part of a user interface (UI), and the colorization is performed to reflect a user's (or some other entity's) choice of color scheme. To perform the colorization, a bitmap may be converted from the red-green-blue (RGB) color space to the hue-saturation-lightness (HSL) color space. The hue may then be rotated toward the selected color scheme. Lightness and alpha (opacity) may be gamma-adjusted toward the selected color scheme. Saturation may be linearly adjusted upward or downward in the direction of the selected color scheme. The transformed HSL representation of the image may then be converted from the HSL space back to the RGB space. The new RGB bitmap may then be used to render one or more UI elements.
