It's hard to see from the screen shot how bad it is compared to any other render. Coming from a TV background, I would never use red font for a variety of reasons, but I'm sure it's important for your use. Is it simply not sharp? Maybe my eyes are getting too old but it doesn't look any different than what I would expect of red text against a green background.
Yeah, its probably just a simple collision of colors, but it looks nasty compared to if the text were blue, black, etc.
Guess I'll just change the color, but thanks for your input!
