  “Colours” are our names for regions of the electromagnetic spectrum. These regions are “constant” – defined by Physics. However, our PERCEPTION of the regions can vary. E.g. some people may be better at ‘seeing’ colours than others. Michael answered this really well in another thread – have a look around!

  No one knows what colours you see, but we can measure the features of light reflected from a surface and give it a name. You might not remember but when you were very little the people caring for you will have spent a lot of time teaching you the names of colours. They spent ages telling you that oranges are orange, grass is green the sky is blue and so on. If you have near average colour vision then those things you call puce (or cerise or any other colour) will look like puce (or cerise… ) to someone else so long as they know what things are puce coloured.
