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

I did, however, remember another crowdfunding platform that may be the best of both worlds here (second highest voted so far being Patreon). Ko-fi: it offers both monthly and one-time donations as well as a store where we could sell things like early access keys or things like that. Their fees are very low as well, capping out at 5%.
