A Splash of Colour

A series of short films on how we see colour

Episode 1: Seeing neurons inside the living eye
Episode 2: Neurons code the colour we see
Episode 3: More than meet the eye: Hyperspectral imaging
Episode 4: Panel discussion: #TheDress – What do we know?

Produced by Dr. Manuel Spitschan, Department of Experimental Psychology, University of Oxford (2018)
Funded by OSA Color Technical Group, International Colour Vision Society (ICVS), Colour Group (GB) & Oxford Vision Group (OxVis).

# Episode Title Description People Date
1 Seeing neurons inside the living eye Using techniques borrowed from astronomy, vision scientists can take high-resolution images of the retina, the fine layer of cells in the back of your eye. Hannah Smithson, Laura Young 06 Nov 2018
2 Neurons code the colour we see All activity in your brain – including those which mediates your perception of colour – is based on electrical messages between neurons. Vision scientists can measure these signals at the eye, and at the back of the brain. Neil Parry 06 Nov 2018
3 More than meet the eye: Hyperspectral imaging How many colours we see is limited by our eye, which contains only three types of colour sensors. Using advanced techniques, vision scientists can take images of this “invisible” information and make it visible. Sérgio Nascimento 06 Nov 2018
4 Panel discussion: #TheDress – What do we know? In early 2015, an image of a dress polarised the internet: Some people saw it as black-blue, and some as white-gold. Three years on, we revisit the dress and discuss how vision science can explain this phenomenon. Manuel Spitschan, Anya Hurlbert, Karl Gegenfurtner, David Brainard 06 Nov 2018
