Offer a colour scheme that more clearly demonstrates the level of nesting. #5
Description
The current colour scheme nests expressions with colours according to the expression type.
- additions are represented with the colour red
- multiplications are represented with the colour blue
- subtractions are represented with the colour green
- divisions are represented with the colour yellow
Consider adding a colour scheme that depends purely on the level of nesting, so that it's easier to comprehend deeply-nested expressions, regardless of the binary operators in use.
