I felt the same way when i upgraded months ago, and i still feel the same way. Someone really needs to re-do the default colors, or go back to the default in version 3.xx which were much better to me.
I have done some color customizations, but i need to do more. There is too much blue being used in the text. I think someone must have decided to copy the colors from the sectional charts. However, on a sectional, the class D and class B airspace altitudes are distinguishable by size of text as well. In skyview, the font size is the same as in this example below.
both have the same text size and similar shades of blue making distinguishing between class B and class D difficult:
100/15 100/25 is class B airspace
20/SFC is class D airspace
