Color vision acuity test. I got a 19. It's probably better termed the monitor color display acuity test; I should try it on different monitors.

You have perfect color vision!
FM Hue Test Results

A lower score is better, with ZERO being the perfect score. The bars above show the regions of the color spectrum where hue discrimination is low.

Got an 8. Cool test.

Haha, I scored 47, which surprises me not at all; I suck at color.

I can't do it! I started and the black separator bars vibrate from the moiré illusion so distractingly that I can't be sure I really see the colors. Very distracting.

They should have designed the squares to not have those black separator bars. The moiré illusion is such a well-known problem!

I had to rub my eyes often to get through it.

I got a fourteen, but the background/image gave me a goddamned migraine. @_@ My eyes still burn.

Yikes! I had to rub my eyes quite a lot to get through it!

20 here - on a monitor I know is crapping out and has color problems. I'd probably do better on my work monitor.

Toby just did it and got a 4. He's got an awesome new 27" iMac -- it better be good!

I did the RL version of that color test - it involved tiles in a tray - as an undergrad, 30+ years ago. (For intro psych, we had to volunteer to be guinea pigs for the grad students.) I scored very well at that point.

Nifty!

I had a number of friends taking Psych intro classes who participated in experiments for part of their grade. :D

I got a 0 on that test! I'm on a MacBook and turned the brightness way up high. It started blurring and I had to blink quite a bit. Really fun test!

Awesome!

Those tree bridges are awesome! I want an excuse for a tree bridge now, though I suspect if I did have access to one I'd spend a lot of time secretly pretending to be an elf walking up and down them... >.> <.<

I got an 8 for the colour acuity test, though my monitor is permanently set to "gaming" and so it tends to be pretty bright and easier to spot differences. I had 4 mistakes at either end of the greeny-blue -> lavender bar, so I guess I wont be using that colour combination any time soon! Nice to know my monitor is properly calibrated despite what photoshop keeps telling me. XD

Wow, that's fascinating and kind of fun. I got a 12 but my gamma's a bit higher than normal.

16 for me, and all my problems were in a narrow band between blue and green. Which isn't too surprising, as lately I've had a little bit of a problem with some of my shirts in the morning, being unable to decide if they are the blueish-green ones or the greenish-blue ones unless I get them into very very bright light. Those shirts didn't used to give me problems.

Can you start to go colorblind with age? Or is purely genetic and doesn't change over time?

I believe that your lens yellows a bit with age -- as a kid, it's sometimes possible to see a little bit past one end of the spectrum, but as the lens yellows, you can't do that anymore.

*googles a bit* Aha! http://www.siggraph.org/education/materials/HyperGraph/color/coloreff.htm

"The lens also absorbs light, it absorbs about twice as much in the blue region as in the red region. As we age the lens yellows, which means it absorbs more in the shorter wavelengths. So the result is that people are more sensitive to longer wavelengths (yellows and oranges) than they are to shorter wavelengths (cyan to blue) and this increases with age. The fluid between the lens and the retina also absorb light and this increases as we age, so the older people get the less sensitive they are to light in general (the apparent brightness level decreases) and especially the sensitivity to blue decreases."

So it makes sense that you're having problems in that part of the spectrum.

My mom had cataracts removed and they give you an artificial lens when they do that, so her color vision should have returned. Man, I wish I'd thought to send her to that color test before her operations and after!
