I have a question.

Why is it that every time something has flashing colors, there's a warning that says "If you have epilepsy, do not use this product" or something like that?

What is it that makes epileptic people not do so well with flashing colors? Just curious.

Very broadly, epilepsy is associated with abnormal 'waves' of neural activity washing across the brain. The frequency things commonly flash at - on the order of once or twice a second - is similar to those abnormal waves and may induce them. AFAIK colour is not the main thing; what matters is the flash rate.

Okay. Thanks for helping me understand!
