![]() A secondary motivation for using a ɣ around those values was that it is close to the typical brightness response to the applied voltage of the electron gun in CRTs, making manufacturing of CRTs easier. Typical values of ɣ are around 2.2 to 2.4 for TV and computer monitor signals. Where V out is the intensity to be displayed, A is a constant, V in is the input level. One way of doing this is to use gamma correction. As the eye can distinguish between closer values of brightness at lower values than higher it is better to use a non-linear color space for recording brightness. When you have only eight bits (or 256 levels) per color channel to store brightness levels you want to maximize the usefulness of those bits. Doubling the intensity does not appear to the eye as doubling the brightness. The eye’s sensors (rods and cones) and the circuitry (neurons) that process the signals are not linear. ![]() But it turns out that this doesn’t match human vision very well. If shining one lamp on a surface produces an intensity of 100 lux, shining two identical lamps produces an intensity of 200 lux. This seems at first like an obvious choice. The first, linearRGB, as the name suggests, describes a color space where the brightness (intensity) of a color is proportional to the numerical value that describes that color. SVG 1.1 specifies two possible values for the color space used while compositing or while interpolating between two color values (as in a gradient or animation). I recently added support for the value linearRGB on SVG property color-interpolation-filters to Inkscape.
