mike dixon Posted September 24, 2013 Share Posted September 24, 2013 How well do you discriminate among colors? Xrite offers an online test of color acuity here: http://www.xrite.com/custom_page.aspx?pageid=77&lang=en A brief article about the test can be found here: http://www.apartmenttherapy.com/how-well-do-you-see-color-173018 I got a score of 15 (zero is perfect).

MichaelChang Posted September 24, 2013 Share Posted September 24, 2013 <p>I might do it another time, but a quick look appears that the test result will also depend on viewing size. Ctl-Scroll on Windows to make that page 300% makes it virtually impossible to get anything less than a perfect score unless you're vision impaired. </p> Link to comment Share on other sites More sharing options...
Mattman944 Posted September 24, 2013 Share Posted September 24, 2013 <p>Not easy, but I got a perfect score. Took me about 10 mins. There is a strategy, but I won't reveal it until other people have tried the test.</p> Link to comment Share on other sites More sharing options...
pbalko Posted September 24, 2013 Share Posted September 24, 2013 <p>Well, considering that the high score for my gender and age range is 1520, I'll settle for the 8 that I got.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted September 24, 2013 Share Posted September 24, 2013 <p>I've taken similar color perception tests before and noticed a huge difference in acuity when I took one while experiencing a migraine. It persuaded me to stick to b&w, unless I'm going for that funky retro faded/shifted color look, because some days I can't even see cyan/magenta shifts, while other days the same flaws are obvious.</p> Link to comment Share on other sites More sharing options...

Dieter Schaefer Posted September 24, 2013 Share Posted September 24, 2013 <p>I have taken the exact same test about 5 years ago and back then got a 23 and on the repeat a 16 and on the second repeat an 8. On the first try now it was 35. If I stare at the color blocks for too long, I get confused and my eyes tire - and some blocks don't seem to fit no matter where I place them. Fairly certain that most of my mistakes are a simple position swap away from being correct. Might try this again when the room is dark.</p> Link to comment Share on other sites More sharing options...

Spearhead Posted September 24, 2013 Share Posted September 24, 2013 <p>4. Interesting, better score than a few years back. All 4 show up next to each other so I guess it's localized. It was also the last row. Maybe if I took more time, I find it gets boring after a while.</p> Music and Portraits Blog: Life in Portugal Link to comment Share on other sites More sharing options...
znabal Posted September 24, 2013 Share Posted September 24, 2013 I took it in 2008 on a cheap LCD monitor I had calibrated "by eye" and got a 7. I passed it on to my family at the time, and looked on while they took it on their various computers. It seemed to me that the monitors made a big difference. My eyes are pretty sensitive to light temperature, the left is about 200K warmer than my right, that may also be an advantage. -jeffl. Link to comment Share on other sites More sharing options...
bethe_fisher Posted September 24, 2013 Share Posted September 24, 2013 There is/was a physical version of this with little round pots of colors (like ones that eyeshadow comes in, if you're at all familiar with those). It was common in some forensic labs to have anyone doing comparison involving color take the tests. In some cases, getting a single one wrong meant you didn't do those cases. With the physical ones, I got a perfect score on two of them and had two shades switched on the other two (I don't remember which). Link to comment Share on other sites More sharing options...
Mattman944 Posted September 24, 2013 Share Posted September 24, 2013 <p>It is sometimes easier to perceive when it is wrong than when it is correct. So, here is the strategy (trick) I used. After I had moved them all and it looked good to me, I went down the line and reversed each pair to see which was better un-reversed or reversed. Sort of like when the eye doctor asks you to choose between two variations of lenses. I found a few that weren't correct.</p> Link to comment Share on other sites More sharing options...

Bill C Posted September 25, 2013 Share Posted September 25, 2013 <p>I don't think anyone should worry too much about the results of this test, at least with respect to your color vision. It's as much about your specific monitor/setup as it is your vision.</p> <p>I'm pretty familiar with the actual test on which this is based, the "FM100 Hue Test" per X-rite, and have seen test results of dozens and dozens of professional color correctors back in the heyday of pro labs. By comparison, the web version is more like a parlor game. Note that X-rite doesn't even call it a "test," they stay with the word "challenge."</p> <p>If you DO get a very good score on the web version, then I agree, you probably have good color discrimination as well as a nicely set up monitor. But if, for example, you get a score of 50 or so (not very good), it might very well be that your color discrimination ability is as good as that of anyone else, but your monitor is somehow deficient.</p> <p>So if you get a poor score, don't automatically assume that there is a deficiency with your vision. Now, if a couple other people outscore you substantially on your own system, then it's a different story.</p> Link to comment Share on other sites More sharing options...
randrew1 Posted September 25, 2013 Share Posted September 25, 2013 <p>I thought I had it nailed and got a 32. That is better than average for my age and gender. I will have to try it again on another monitor. I may also try viewing through separation filters. </p> Link to comment Share on other sites More sharing options...
randrew1 Posted September 25, 2013 Share Posted September 25, 2013 Scored 10 on my MacBook Pro with Retina Display. Better than the generic monitor at work. Link to comment Share on other sites More sharing options...
lex_jenkins Posted September 25, 2013 Share Posted September 25, 2013 <p>Got a 3 on my second attempt, a day later, after recalibrating my monitor and waiting until the room was darker. I also took a few breaks to let my eyes rest. But I'm still prone to error in the same green/blue-green cluster, which is probably why I have difficulty some days accurately estimating skin colors.</p> Link to comment Share on other sites More sharing options...
LineMartel Posted September 30, 2013 Share Posted September 30, 2013 <p>I don't see how this test, results, and comparison to others could be in any way accurate. To be accurate, everyone would have to see it on the exact same monitor, with the same exact ambient light...</p> Link to comment Share on other sites More sharing options...
MichaelChang Posted September 30, 2013 Share Posted September 30, 2013 <p>Line, I think the test should not be described as "accurate"; rather more "valid" or not.</p> <p>Turns out the test is indeed valid because it's looking for vision monotonicity, or put another way, the eye's ability to discern minute differences in colour gradation over some defined range.</p> <p>Monitor and ambient light differences will only make the test (slightly) more or less challenging because it's more difficult to discern differences under low(er) light - resulting in a hue shift, but the gradation remains the same.</p> <p>I would agree with you if the test was designed to reveal ones ability in absolute colour recognition.</p> <p>The only objection I have about the test is that the colours are generated by a light source rather than reflected light as naturally occurring on Earth - we as photographers are rarely required to discern differences in colours of light sources.</p> <p> </p> Link to comment Share on other sites More sharing options...
