SpeQ Mathematics might be a bit more popular than Moodle. We know about 1 link to it since March 2021 and only 1 link to Moodle. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Moodle can handle this but it might be overkill for your requirements. Once you have it setup though the quiz feature is really great, and the analytics it provides are awesome. Source: about 1 year ago
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: about 2 years ago
