To your own taste. Pavilion, crown and table combined. Same, after resizing, sharpening and adjusting brightness and contrast. Colored faceted gems are done the same way as diamonds, with one exception. Instead of using the iridescent tiles, we will be selecting one color and its different values.
Color value refers to where it stands on the light to dark scale.
Unless you want to create special effects, the values of a color are all located on the vertical axis of the square in your color palette. Moving to the left dulls the color and makes it closer and closer to gray. So, once you have selected a base color, dark is straight up and light is straight down. I am referring here, to the direction in which, you need to move the little circle, in the square color palette. This being said, the technique is exactly the same as the diamond.
