Different devices (monitors, printers, scanners, and cameras) process different colors. Each device has a range of supported color values. Colors supported by one device may not be supported by other devices.To effectively use the color and understand the functions used in quartz 2d for color and color space, we need t
The first thing to declare is that this 4-digit (16) color map is special, rather than a 16-color map, it's just a gray-scale map that uses 4-digit 16 colors for simulation.

above weights are developed by means of a TV signal, which is the only one of the linear RGB component values, that is, a signal that does not contain gamma (gamma) correction. However, in many cases, the RGB component value is non-linear, in this case, in order to apply the above weights to get the correct brightness, the RGB component must first be linearized. Another solution is to estimate gray values without linearization, which requires a set of different weights to be used to sum the non
