ditto that. Most of the time I don't notice the effects of red-green color deficiency, but whenever someone wants to differentiate between A and B with colors, inevitably it's red/green.
Not much to do about it with xmas colors though. Bah humbug to poinsettias.
At a glance it looks gray and gray. If I stare, I can make out the red and can see that the green is a different color, but I really only recognize that it's green because people mentioned it being green.
So, I concur with the bah humbug to colorblindness statements.
I didn't even notice the colored numbers until I read the comments. For myself, the colors are easy enough to distinguish (as separate colors), as the red looks brighter than the green.
If I didn't already know the colors were red and green, I think I'd be able to pick out the one that is clearly red (As there is a shade of red for sure in the title bar), but I do not believe I'd be able to say with certainty that the green is green (and not another shade of red).
