Understanding Short Term Colour Memory

Do people perceive colours on a computer screen the same way they as when they see them printed on paper? This human visual perception study measured some telling results.

Case Study: Comparing how people remember printed and computer-displayed colours

Do people perceive colours on a computer screen the same way they as when they see them printed on paper? This human visual perception study measured some telling results.

Aim

To establish if people remember the colour of real papers and those in a computer screen in the same way.

Funding

Federation of Ophthalmic and Dispensing Opticians

Project

We used controlled paper samples that were carefully measured and characterised and produced physically accurate reproductions that could be displayed on 42 bit calibrated display. We then used techniques of applied psychology to design a colour memory task that was performed by a group of participants after careful screening of their colour vision.

Results

From analysis of participants' responses we were able to establish that there is little difference in how people recall real and computer displayed colours when all physical and physiological factors are taken into account
