I have the same issues; for me the red is much larger than the rest and the yellow one is pulsating. I have it with everything involving rasters and some colors. Actually some patterns make me nauseous (not this one though).
I'm not bothered much by it, but I avoid, while making things, combinations that make this happen.
I don't know if it is because I am slightly color blind (on tests I can usually read maybe 1 of those blotted spots with letters/digits in them; http://www.toledo-bend.com/colorblind/Ishihara.asp => I can only see the top left one, which is the tester if you're not totally blind I think :), the rest is just random spots. People who don't have this issue might think I cannot see colors at all but I can; it's only in combination it might go wrong.), but it's worse when i'm tired.
The best freak show is a big squared 'tent', but with small squares of 2 horrible colors, like red + green/blue in bright power-saving-lights inside, for instance, a shopping mall and me not having had the best night sleep. Then I see these effects really well and actually have to move away from the offending object quite rapidly.

Edit: I mean 'checkered' not squared, so like http://www.schnittmuster-stoffe.de/images/product_images/pop... but then preferably plastic material, bad, bright colors and preferably so big I cannot look around it.
