Rainbow colored bread in the 90s?

I’ve found that people (including myself) react differently according to the source of the colour (assuming they know the source). Mashed potatoes dyed purple with food colouring would put me off. Purple mash made from blue potatoes positively excites me.
It’s a ‘natural’ vs ‘artificial’ thing - not entirely rational, but it’s a strong force.

I wonder if our inner cave person is going “ITS MOLDY! ITS MOLDY!”.
