Guild Wars 2

In the Snowblind fractal, the Ice Elemental fight contains a very strong white and blue effect that occurs when players are teleported around at random.

It is brutally painful every time it flashes on screen, even with my added color and contrast adjustments to minimize what effects like this can do to me. Is it possible to lessen the effect at all or take it out entirely?

I support this, and any other thread that asks to tone down the seizure inducing particle effects and bright lights. The only game worse than this one for seizure that I can think of is Mass Effect 3. If you play a vanguard you will have a headache in 5 minutes and a stroke in 15

You could always turn off post processing effects.
