But what particular impact for medium blue for example?  I didn't read the article. 
Yep, mine came that way and will stay until I get around to a re-do.  Not sure what you would call the color, somewhat a darkish beige?  Plus the lights themselves are adjustable from white to other colors with various effects if I want.  No matter what I've set in the way of color I don't find that it particularly affects my perception of color on screen, i.e not any particular changes with the tv, tv still looks right to me.
