how much green, white, warm yellow, burnt umber, does it take to make a cucumber?

I have been very interested in artificial food. How and why do they make it?
These drawings are an exploration in to the colours that I used to mix with silicone to create plastic cucumber ends.
I wanted to explore these mixing of oily colours on paper. I also wanted to experiment with peanut oil and see how the oils glided with the light bodied oil.
