Dear ImageJ community,
today I am writing you to ask you for a little support in an experiment for better determining perceived color differences.
http://colors.htw-berlin.de/The exact determination of perceived color differences is very difficult. Typically, color differences are calculated from color coordinates using special metrics. Unfortunately, these distance measures (like DeltaE CIE76 or CIE2000) do not always coincide with the perceived differences. We have designed an experiment with which we try to model better color metrics. The basic idea is to present color triplets and let people decide which of two colors is more similar to a reference color. Unfortunately the number of experiments is extremely high and the individual tests are rather "boring". To address this problem, we have designed a game, in which the players provide information about the perceived color differences.
It would be of great help if you could play our game for a little while and/or let other people know about it:
http://colors.htw-berlin.de/Thank you very much!
If you interested in knowing more about the results (it will take some time before they are finished), please write me an email.
I can also send a paper that we have written about this approach (however it is in German).
Best,
Kai
