Change the color of the DepthString based on it's deepness

Browse source 
Change the color of the DepthString based on it's deepness
on the profile planner. The new color of the profileString
( the string that follows the mouse stating how deep you are)
is now interpolated from SAMPLE_SHALLOW and SAMPLE_DEEP -
but since those two colors were the same and I had to change
it so that could work, I want somebody to check if my choose
of colors were ok.
