Can't read red text on blue for Invalid Choices

[beamersrq]

Is there any way to change the red text on dark blue background that is used for invalid choices, both in the listing and description of why it's invalid? I'm mildly colorblind (red/green which is very common) and cannot read it without dragging my mouse over it to highlight it. I can see there's text there but the contrast isn't enough to read it. I've never had much of an issue with other sites, just this color combo.
