glColorIntegerui

glColorIntegerui is a function in OpenGL that sets the current unsigned integer color values. It is used to specify the color components for subsequent rendering operations. Unlike functions that set floating-point color values, glColorIntegerui operates on unsigned integer types. The function takes a variable number of arguments, representing the red, green, blue, and alpha components of the color. These components are treated as unsigned integers. The range of values for each component depends on the implementation but typically spans from 0 to the maximum value representable by the unsigned integer type used. When this color is applied to a fragment, the integer values are typically scaled and converted to floating-point values in the range [0, 1] for further processing in the rendering pipeline. This scaling is usually performed by dividing each integer component by the maximum representable value for its type. glColorIntegerui is particularly useful when working with fixed-point or integer-based color representations.
