Or, “color light value” is the amount of light and light radiation that a color approaches the viewer’s eyes. the colors of the Macmear to its brightness without changing the effect of their color, “goat” in the theory of their colors to each color of the first category or second and secondary color, which is proportional to its optical value, the ratios that are made between numbers. This will make a bit of the corresponding colors carefully, although these numbers and methods can’t be accepted as the main fixed and permanent principle, an example of the numbers discussed as:1-d is equal to the number 9. 2 is equal to number 8. 3 red is equal to number 6. ultraviolet is equal to 3. It means that, for example, yellow light is three times purple, so if the ratio between these two colors is balanced, the level occupied by purple should be three times as high as the level occupied by yellow (with-leader)
