The colors that can be set in the converter are simple Plus/4 color codes, just not in hexadecimal format. Values greater than 127 are actually redundant, and repeat the colors from 0 to 127. The color code can be calculated as 16*L+C, where L is the luminance (0 to 7), and C is the color (0=black, 1=white, ..., 15=light green). For example, 0, 16, 32, 48, 64, 80, 96, and 112 are all black, while 15, 31, 47, 63, 79, 95, 111, and 127 are light green with increasing luminance. A quick way to find colors is to click on the number, and drag the mouse left or right, as if using a slider; this will adjust the value, and when you release the mouse button, the color will be shown in the square next to the number. Note that this dragging trick also works on all the other number inputs, and in the emulator as well.
