-You should include one line for every foreground color setting. But the calculator Rom bounds the contrast setting with the keyboard to useful values. The HP48S/SX Rom use values between 3 and 19, the HP48G/GX Rom use values between 9 and 24. Remember this when you write the color table please. The other three integers are the RGB numbers (Red, Green, Blue). The RGB numbers range from 0 to 255. The background color number for the corresponding foreground color is always calculated by adding the first background number setting to the color value. If the background color for the contrast setting isn't defined, color 0 is used by the emulators Emu28, Emu42 and Emu48 and transparent mode by Emu32.\par

+\page But the calculator Rom bounds the contrast setting with the keyboard to useful values for each calculator model. The easiest way to generate reasonable contrast settings is to put the calculator to lowest possible darkness value by keyboard and enter the corresponding RGB values to your KML script at the lowest possible setting by ROM (background = pixel off color, foreground = near to background color). In the next step put the calculator to highest possible darkness value by keyboard and enter the corresponding RGB values to your KML script at the highest possible setting by ROM (background = pixel on color, foreground = near to background color). Next important point is the darkness reset value of the Rom because this should be the point of best contrast between fore- and background color. So in the first range between lowest darkness and reset point, use the pixel off color for all background colors and calculated RGB values by a nearly equal distance algorithm for each color part for the foreground colors. For the second range between reset point and highest darkness use the foreground pixel color of the reset point for all foreground colors and calculated RGB values by a nearly equal distance algorithm for each color part for the background colors.\par

+The contrast settings outside these areas (accessible by hardware so it\rquote s not useless) can be calculated by the distance between each color channel with saturation to no contrast at pixel off on one side, and pixel on the other side.\par
