Red doesn't really bother me as long as it tastes great
It's odd what a (psychological) difference colour can make. I once had a takeaway curry from Ababil, at Crossways (New Eltham), and was convinced that they had used chicken cooked in the tandoor -- it just didn't taste right. So I challenged the owner (in a friendly way) on my next visit, and he laughed : "No Sir", he said", "not cooked in the tandoor ... but the chef had dropped a tin of red food colouring and it had gone everywhere !". So the more gullible amongst us are certainly capable of being subconsciously affected by colour, even if the more rational are not ...
