At the risk of sounding pedantic or critical (it is but only in the helpful well, I assure you) -- the word 'ridiculous' comes from the Latin 'rideo' which means to laugh, which is in contemporary French 'rire', Italian 'ridere' and English 'ridicule'. It has nothing to do with the color 'red', if that helps you remember that it does not have the word 'red' in it. As well, you can associate 'rideo' with 'video'.
