Resource Pack Font colors break in title or actionbar depending on GUI scale

When a custom font is in use by a resource pack that includes colored characters within a title, subtitle, or action bar, if the GUI scale isn't the default, the colors become crushed.

I attached a screenshot that shows a title and an action bar in GUI scale 0 and -1.

Steps to Reproduce:
1. Use a resource pack (or join a server with a pack) that uses a custom font
2. Use a GUI scale setting other than the default 0 scale.
3. Observe the discolored UI inside titles, subtitles, and the action bar

Observed Results:
The font color is distorted and the displayed sprite loses color quality

Expected Results:
The color of the UI should be consistent regardless of UI scale
