I don't get what you need to know 0 is dark, 255 is light. As you already said its R G B. Are you sure you are reshowing the Textdraw after applying the color? Otherwise your changes won't be seen till its redrawn.


[Edit]
Red (well a crimson rather good for a speedo) = rgb(220, 20, 60)
Yellow = rgb(238, 238, 0)
Green = rgb(131, 245, 44)

Never go to 255 across all colors that's white, even going to say 250 tends to be a washed out color.
