Interesting. I suspect if I took that test I'd show up as pretty much impervious to the colour of food. I've often thought it strange that they feed pink dye to farm salmon because otherwise the product turns out grey and that puts people off buying it. Me, if I ate fish at all, I'd rather it be grey than have to eat food dye. I'm not that scared of the dye they use, just that it's a bit of an unknown risk - some say it's harmless, others say it's dangerous, so how the hell do I know, so I have to conclude that there's a question mark on it, and to me it makes sense to avoid eating something that's of questionable safety without a good reason. Same with coloured tablets - I hear they encourage some folks to buy more if the uppers are red and the downers are blue, and the colouring might have a placebo effect on some people, but in my case the presence of useless additives just puts me off buying them and I very much doubt the placebo effect would work on me, I think I'd just worry about the dye I'd eaten. It'd make a good study, testing whether or not the colour of ingestables makes less difference to Aspies than it makes to NTs.
