TrueType fonts are not multi-colored and I believe the outline, the white in your image, is the actual font data and the black inside the outline is empty pixels showing the black background. There’s not really much you can do to change that.
You do know that you can add an outline to any font using the outline property of the font? And you can control the color of both the font glyph and the outline.
Thanks, yeah i must have missed that and did not set the outline width correctly. I dived a bit into Bitmap and distance field fonts and I got it now. The Doc was great on that topic. Thank you
