has anybody experienced having a child with autism and or epilepsy having fits with the colour yellow?

I have a friend who has a child with autism and epilepsy.
They thought the child ( who is disabled and unable to talk) loved the colour yellow but have recently found out that the colour yellow was a stimuli and it gave her fits.
Does anyone have more information about this or know of any good websites where I can find more information about this or maybe have dealt with this problem themselves?
