Just for your information, the lunch doesn't look particularly colourful. It's about 95% green except for the smoothie which is a uniform (and bright!) orange.
It
does have a wide variety of tonal values which, as a colourblind person, may be what you're picking up on. Interesting how "colourful" means different things to different people.
It's much the same story for breakfast and dinner - heavily dominated by green (with blue from the blueberries in the morning and largely colourless pears).
P.S.
I'm impressed by the 36 pushups. At the moment I'm having trouble getting past 3.6
