[cBB Blockgets 1.0.3] Frame block text color

Hi,
I was testing Frame block with *.txt file and it works great on light styles, but when I use dark style there is problem with black text color on dark background. Maybe I missed something, but it is possible somehow to change color of text to default text color of the board (it would solve problem with any background) or use for *.txt files white background (as is normal for *.txt files, but I would prefer the first option)?
You can see it here.
