Title: Make rainbow delimiters less intrusive and less confusing 

Solved problems:

-- Red is too striking and leads to unnecessary distraction. It was placed
right in the middle of the spectrum.

-- Red and orange where in immediate succession which made them difficult to
distinguish.

-- Order wasn't cyclical, but rather random.

New order is [blue, orange, green, yellow], and not a real rainbow [blue,
green, orange, yellow], because it is easier to distinguish the sequential
levels this way.
