The physics and psychology of colour (Andrew Hanson)

Andrew Hanson will elaborate on his own area of work – colour measurement. Colour informs, influences consumer choices, warns us and comforts us. As with every aspect of life, it needs to be measured to ensure good communication and confidence in manufacturing processes for a diverse range of goods from pills to paints. But how do we ascribe numbers to a human perception which is incredibly versatile and variable? The challenge is enormous and human colour perception science is still a lively topic today. Be warned! This demonstration talk will contain surprises – there is a lot more to colour than meets the eye.
