Agreed. I would also like to add that colour perception is influenced by ambient light so it isn't even a display issue. On my wide monitor I perceive the same hex-value colour differently on the left and right sides (because half is in front of the window and the other half has a wall behind it). > And it's important the the colours work even if one is colourblind. > I'd suggest viewing it converted to greyscale as a first try at testing > this, bt a friend of mine who is colourblind tells me it's far more > complicated than this. Yup. Red/green colour blindness is most common but there are many more varieties and some involve more than two colours. A greyscale version is a good first approximation to check whether colours can be told apart in case of colour blindness.
