45, just a little better than average based on the scale at the bottom of the page. ---

Eek, I did this some time ago and got a 0, and just now I got a 22. Of course, my monitor is much older now. But so are my eyes. ---

0 for me. My better half is one of those rarer color-blind women-folk, though. And she’s left-handed. And a lesbian. Sadly, she has crappy luck gambling. ---

Because I deal with color in my job I viewed it as a challenge to do well, and probably spent 12 minutes moving many of the chips back and forth with their neighbors… but eventually got bored and said _enough_. ---

> [@njtt](#): > > and in brighter light (normal daylight illumination, or indoors with the lights on) peripheral vision is subserved by the handful of blue-sensitive cones that are out on the periphery. Huh–that I did not know. I knew that dark-adapted rods could saturate easily (which is why dark adaptation is so easily lost), but didn’t know that there was another saturation point well before normal bright conditions. > [@njtt](#): > > I would doubt that brightness is an issue either. If this teat has been constructed properly, the patches should have been equalized for brightness. In principle, yes–but that’s the kind of thing that an uncalibrated monitor could easily throw off. Somewhat ironically, calibration could make this test more difficult. > [@njtt](#): > > Surprising as it may seem, there is evidence from recent experiments that eye movements do play a role in color vision. With this test, I found that after I had got things in fairly good order, it helped to move my eyes back and forth along the color line, looking for uneven transitions. I found a few that I had not noticed when looking just at two or three adjacent patches at a time. Not too surprising to me but interesting nevertheless. The random distribution of receptors helps with detail as well–intuitively, you would expect the detail limit of the eye to be on the order of the receptor spacing, but in fact it’s much higher than that for certain cases (vernier acuity is the quintessential example–the ability to line up two offset lines). I’m not sure that the reason is known for certain, but it’s a pretty good guess that the eye uses the stochastic distribution to make extra inferences about the position of the lines. You couldn’t really do this if the receptors were in a perfect grid. ---

I got a 7, which I thought was good until I saw most people here got like a 4 or a 0. So I’m just gonna say I didn’t try very hard, I’m tired from working in the office all day, the computer monitor is cheap, and you guys are probably pulling our legs anyway. I had troubles with the turqouis here too, and knew I was having trouble with it during the test. It didn’t surprise me that the results showed that was my weak area.

> [@Kenm](#): > > Is it worth the time to do the test when probably every monitor used in this thread has different colour characteristics? Precisely the problem. I know the way my monitor is set up that certain hues are mixed up–I can go compare it on another monitor. Though LCDs are much more accurate that CRTs were. It’s probably not going to be off by more than 100 or so. ---

> [@panache45](#): > > The test is about \*relative \*colors, and has little to do with calibration. You could do the test on 100 monitors, all calibrated differently, and the results should be the same . . . except for some really crappy monitors, or displays with only 256 colors. That’s full out wrong. I know for certain there are times where a bright yellow will, when, made brighter, take on a green tint, and then, a bit brighter still, will lose it. I also know it looks perfectly fine on the LCD monitor that is more correctly calibrated. Furthermore, if one color is brighter than another, then rather than seeming like continuous color, it will seem like it gets brighter all the sudden, and thus look wrong. You can only do this measurement if the brightness is either the same or contiguous, otherwise the color differences are too small. ---
