chemical additives

A few weeks ago I posted about the safety of food colours. My argument was that the issue is not whether food additives are natural or man-made (let’s even say chemical because that really sounds nasty – even though water is a chemical and we are made of chemicals). Rather, the issue is whether any additives are safe or not, since plenty of natural products are highly dangerous (even fatal) and the vast majority of man-made additives are perfectly safe. My good friend, Mark Bishop (Professor at Goldsmiths) commented that maybe people feel safer with natural additives because they have been around for longer and so we are more certain about whether they are safe or not. He may have a point – today it was revealed that 4-methylimidazole (which is added to Pepsi and Coca-Cola) is carcinogenic. Presumably this chemical was once thought to be safe.

meaning of red

Today I found Karen Haller’s blog post on the meaning of red.

I liked the fact that she wrote about positive (warmth, excitement, energy) and negative (aggressive, confrontational) connotations of the colour. Karen argues that companies that use red as their primary colour are aggressive and energetic with a buzz about them. She gives examples of vodafone, coca cola, and virgin. Do you agree with her?
