Colour - Not what it seems? Optical Illusions from R Beau Lotto
Colour is a complicated thing. It should be quite simple, but it isnt. Ink printed onto paper can be compared one with another, relatively easily (under standardised lighting).
Monitors are trickier... but eventually they can be calibrated, colour 'spaces' unified and so on to attempt to get technically identical colours rendered loking like they are the same colour...... but nothing really prepares you for just how different they can look once you've got everything technically perfect!
The juxta position of colour and..... the brain!!
