These towels looked nice and felt soft when I first received them but after only a few weeks of normal use, they are discolored.  I bought 2 sets of the grey color and there are now big splotches of pink on many of them.  I have a different set of towels in blue from another manufacturer which I have had and used for over a year and these are not discolored at all, so this discoloration is the fault of the towels and not something I'm using on them.
