Ruthless is a nice pale chocolately taupe. I could never really tell much of a difference between UD's deluxe shadow formula and their regular formula save that this one feels a bit softer. In the deluxe line, the brights were always very popular, but I personally preferred the neutrals more. Ruthless is the only one that I kept, because in spite of the fact that I have dozens of light neutral shadows, this one is special. I believe these were discontinued some time ago, but I highly recommend it if you can find it.
