A SPLASH OF COLOUR

1. Seeing neurons  in the living human 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.

2. Neurons code the colours 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.

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. 

With Manuel Spitschan, Anya Hurlbert, Karl Gegenfurtner and David Brainard.

3. More than meets 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.

On these pages, we present videos which have been produced with the support of ICVS.

A SPLASH OF COLOUR

In this video series, we explore human colour vision and colour perception through the lens of neuroscientists, psychologists, and physicists working in the field. We examine how light hitting the back surface of our eye leads to signals in the cones and rods and how these can be measured using modern non-invasive techniques, how spectral imaging can allow us to "see" what the human eye cannot, and also examine what we learned from #TheDress.
