Colour Clock and Hue testerI thought it would be fun to see if I could tell the time using a Hue clock, and then it occurred to me that I could also use it as a serious tool for testing how well I could distinguish different Hues.
Now the serious aspect... We can run the clock in a slightly different mode to see how easy it is to tell changes in Hue - the whole clock changes from one hue to another at random-ish intervals. Unless you are perfect (i.e. a woman) and have an excellent display (i.e. expensive), I think you will not be able to tell all the Hues apart. I've included three hue shift increments, starting with 12 changes (i.e. the same as the hours on the clock), down to seconds (or 6 degrees of change). Every time the clock changes hue you need to press any key (spacebar is easiest) to say you have seen the change, and then at the end it will display which hue changes you missed.
I think the results are quite important in how we adjust and see images on the screen - if we can not differentiate certain hues, then we either need a Hue Watcher to tell us different shades, or we can skip being too accurate! If you think this could be interesting, then there is an option to email me your results and when I get enough of them, I'll add a chart (to this page) showing which hues are difficult to tell apart by people on their screens. If you wish to use the program, just download it (virus checked by avast), unzip it and place the program on your PC (sorry it will not work on Macs) and create a short-cut to it. The program is completely free. |
