in my experience, color rendition is the opposite, Do NOT use red when looking for red stuff, etc.  I used a red LED on a map one night in the car, couldn't see the road's for sh*t.  Even the blue lines of waterways were tough to find, but at least readable.  Anything with red ink was gone. 
As I understand it, and will soon be testing, that is the idea:  wash out the background color so the shadows of tracks stand out.  Use yellow on sand and the sand "disappears", for example.
