128-bit

128-bit refers to one hundred twenty-eight (0 or 1) units of integer data. This allows for up to 340,282,366,920,938,463,463,374,607,431,768,211,456 combinations of values.
*128-bit color is split into four sets of 32-bit values for 4,294,967,296 levels per RGBAf channel (red, green, blue, and alpha with ). The three 32-bit RGB values would deliver 79,228,162,514,264,337,593,543,950,336 unique colors, the same as 96-bit floating-point color, but with the addition of 4,294,967,296 levels of transparency defined by the alpha channel.
