There are different methods of doing hardcoat.
When we used to do conventional hardcoat, you would end up with the coating producing a color from grey to greyish bronze & it would be hard to dye that a decorative color, like red. Black was really the only option available.
Now that we run a different method of hardcoat, with a additive, which still meets the mil-spec, the finish comes out almost colorless, & yes, it can be dyed red & other decorative colors.

You can dye the traditional hardcoat red, but it will come out a dark burgundy color. It looks good, but it won't be a bright "fire engine" red that your customer may want.
