Level Font graphics has gray pixels when it changes color.
I briefly mentioned this in the more whitelisted colors post but I figure maybe this is perhaps better suited as a bug report about it, perhaps?
You can apply a colormap to the level font if you add in something like
\82yourlevelnamehere as your levelname. This will change the font to use a yellow colormap. Upon looking closely at the level name appearing as a different color... you'll notice that there's some gray pixels on the font as shown in this image below.
I changed the gray pixels that were used for the level font with the gray pixels from the console font. Upon doing this... the levelname changes color with no stray pixels now.
I have included a pk3 file which has the altered Levelfont graphics. Greenflower Zone 1's Levelname was edited to allow it to show up with a yellow colormap although you can see the yellow colormap without any addons if you obtain the last chaos emerald from the special stage.
Updated pk3 file as the , had a incorrect offset.
