Simulating Colour Perception With Ageing

How Do You See the World While You Are Aging?

On average, the crystals in our eyeballs get yellow blur at the age of 50 due to UV irradiation, which means the colours we see will gradually get more yellow than before and this procedure happens so slowly that most people won’t notice.

Using Processing, this project simulated colour perception with ageing via the cameras of computers and provides a visual reference for design projects involving with colour perceptions for the elderly.


The handout design of the project investigated a physical representation of yellow blur by overlaying a sheet of a tracing paper and yellow perspex on top of the text. The three layers stick together because of the static electricity, and the text looks black. However when revealing the top two layers, the experiencers will notice that the colour of the text is actually indigo, which illustrates the invisible change in colour perception while ageing.
