Mine's black. Maybe it is the red pigment.... Red does fade fastest
..... I remember when I was little and my Mum used to buyour school shirts in Tescos.. the label name was 'School Days' and the letters were in alternate red and blue. After a few washes the red letters would completely fad away and leave the label saying 'Shody'
That's when I first realised Red doesn't have much staying power
