black

because for there to be no heat, there can be no light either.

does everything harmfull have a colour? Is headache green, red...?Heat has no colour, even fire can take very different colours( from red to blue). The colour that water takes at the least teperatures is white or is even colourless, depending on it's condensation (pressure). Colours can have a thermo-effect on people (maybe animals too) : red for exemple or orange colours give an effect of warm, blue is the most cold colour. Designers and advertisers use colours to have that effect or other effects ( calm, vitality, awkeness....)

BECAUSE cold does not exist.

Cold is the absence of Heat.

The coldest cold would be if somehow you could
remove all the heat from everything such as in a
perfect vacuum in perfect darkness. There is no
color for absence of something.

However, it is common practice on maps and things
like that to use Red for Hot and Blue for Cold. Maybe
that is because when we get cold we turn blue. When
we get hot we turn red.

colours as a warning of harmfulness is connected with sentient life, which has no real relationship with low temperatures except through thick fur.

as for the second part of your question: i don't get it - surely a very very cold strawberry is still red? If not, I'd like to know

PS I like dr obvious' answer but if the coloured thing is highly reflective of one colour of light and highly transmissive of another, it can still be pretty close to absolute zero and still have a colour

there's no direct relationship between colour & temperature.

but in the same vein as Dr Obvious's anwerer :wouldn't his black object absorb all the energy around it, making no longer the coldest of the cold? :-p

A very shiney object would be better
