Colors for sketch elements& viewport environment.

Sometimes I would like to change environment colors / themes to sort of relief eye strain, but I found I'm stuck with Grey Room. 3 out of 5 are borderline unusable especially in the sketch mode, constrained lines and dimensions are in the same color, in Dark Sky / Photo Booth / Infinity Pool environments. That leaves me with Grey Room / Tranquility Blue, oh wait, who would stares at a BLUE screen for hours? Alright the blueprint theme might be cool for making screenshots but simply not great to work with, that's it, I'm stuck with Grey Room. 

Okay, rant is over, time for some constructive suggestions:

• Differentiate colors for different sketch elements, for ALL themes.
• Adjust environment theme colors so all of them are suitable to work with (not just cool to look at)
• Or, better yet, make them customizable.
• Some may suggested this already, color options for UI, simply different shades of grey would be nice.

I'm facing the same situation in the drawing mode. The only available color is white and I am trying to get more options available for background use.
