Some really nice use of fades there. However the font backgrounds are not quite black, it's close, but not black (actual rgb colour seems to be 4,2,4).
I assume this is an artefact of fading the colours up and it's adding a little too much at the final stage. I guess either twiddle the final fade values or generate a mask for the font as well and simply avoid the issue.
Unless of course, the original had this issue as well
