In my past '
Radiocraft' days, I had some success printing HMV transfers on white water slide paper
using brown in the 'clear' areas.
Inevitably, this entailed several print trials, both to tone down the brightness of the logo itself and to get the shade and tint of brown right. The adjustments were carried out in Paint Shop Pro. The area of brown was small. The eye readily accepted it and didn't spot the lack of grain.
