RGB East

When you play this video please stare directly at the cross in the middle of the screen.

Did you see the lilac circle? Play the video back and try to follow the circle to see it isn’t really there!

This illusion is called a negative afterimage. For a full explanation of how it works, please upload a photograph to our web page. You will then receive a new illusion made from your photograph and a full explanation of how it works!

About the Project


RGB East – a platform to explore the connection between digital photography, perception, and colour.


RGB stands for red, green, and blue, which are the colours that the light-sensitive cells in our eyes are sensitive to. These colours are also used on our computer screens and in photography because they can be combined in various proportions to obtain any colour in the visible spectrum.


RGB East was seed funded via UCL’s Trellis Programme Stage 1. and opened for submission in Summer 2020. and is currently funded by UCL’s Beacon Bursary Programme.


To use the RGB platform, you are invited to take a colourful photograph when you are out and about in the four boroughs of Hackney, Newham, Tower Hamlets and Waltham Forest.


The next step is to upload your chosen photograph from one or more of these boroughs via the link on this page. Your photo will appear on the map which will be accessible to be viewed by all.


You will individually receive a link to a visual illusion using the photograph you send us. This illusion will enable you to consider whether:


• the colour we “see” exists in the external world or is created through a complex interaction between our eyes and our brains;

• we all see and experience colour in the same way or differently from one another.


By considering the colouration of the image you uploaded, you will be contributing to an ongoing collaborative digital photography project recording images from East London. If this is of interest to you, please see the submissions page.


Currently, we are collaborating with Into Focus, who are part of Four Corners portfolio of activity, on an intergenerational analogue photographic project funded by UCL’s Beacon Bursary. This will culminate in an art exhibition in Summer 2021. Your submission(s) to this page may also be part of a future exhibition so if you are interested in having your images displayed please remember to tick the consent box in the submissions page.
