My favorite that fits your request is SpeQ Mathmatics. For rolling dice use the command RandInt (random integer) along with the lowest and highest values. For your RGB example you would enter (RandInt( 1,255 ), RandInt( 1,255 ), RandInt( 1,255 )). Pressing F5 generates a new set of results. Source: almost 2 years ago
