Lotus. The car manufacturer, because I have no idea who those two are in the context you intended Oversaturation or grayscale?
Scrooge. Because he has more cache. Also, i had to think a bit about who scrooge is as his german name is waaaaaay different xD German or English?
So far the sequals, but, there's only one, yet. But I still liked the prequals Astronomy or Quantum Physics?
Noisy family, because at least you don't have to scramble out of bed, normally. Cold water or hot water?
