Web1 de jul. de 2014 · For example, an 80% black on white equates to a gray of 255 * .80 = 204 or RGB (204, 204, 204). Things get a little more complicated, however, when dealing with shades other than a white background and a black overlay. The relationship of color and transparency can be generalized by the following compositing formula. Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called bremsstrahlung).
