I already know that I'm colourblind, but if anyone else is curious what those results would look like; Here ya go: http://imgur.com/a/OgnuM

Something of interest that I noticed is the fairly constant gap between areas of low colour acuity

I didn't concentrate too much but still wonder if my score of 49 is something I should be worried about? http://i.imgur.com/WqRonYi.png
Why worry about something you can't fix? (Unless, of course, your monitor, not your vision, is the problem.) Unless you "do colour" for a living and have wondered why clients aren't banging down your door, it's probably not a real-world problem for you. (If it was a problem severe enough to be a safety hazard or mangle your fashion sense to the point that a hypothetical Garanimals For Grownups might be helpful, you would probably be acutely aware of it by now.) Hell, there's even at least one "name" professional photographer (Joel Grimes) who would score worse than you did. (Your problem is relatively subtle, apart from a bit of a mess in the red/yellow/green transition. You would probably have some real difficulty distinguishing the yellows of an egg yolk, a buttercup and a lemon, or at least being able to spot them in isolation. As handicaps go, I've seen worse.)
Well, I also do front-end web development from time to time and when I do, maybe I should consider having much more external advice on design matters than before. I never thought I had any problems, that's what worried me. Thank you very much for the explanation.
I wouldn't put too much weight on it...

I tried it without much effort on my so-so Dell desktop display and got 59. Tried again on my RMBP with even less effort and got 14. However, I did have trouble in the same places both times so it's certainly demonstrating something.

I'm also using a Dell display. Maybe I should fiddle with the settings a bit.
Interesting--I got a 16, but your spectra look very close to accurate to me. How severe is your colorblindness? Does it affect your daily life?
The optometrist I go to said it was a pretty severe case of colourblindness, however compared to other colourblind people I know, its not too bad. I have 2 cousins who fully cannot distinguish red from green, where as I think of mine to be closer to an optical illusion.

Green/Red street lights are easy to tell apart, but the amber light in the middle can look very close to either depending on the light level outside. A red flower amongst a green leaves is something I would overlook, unless it was pointed out to me. Then I would have to search for the flower. While looking directly at it, its pretty apparent its different from the green leaves but to spot it without previous knowledge that its there is a difficult task (This situation came up yesterday while someone was pointing out a wild rose among a hedge.).

Overall it I would say it doesn't have an effect on my daily life. I can still wire up a RJ-45 connector under good light conditions (I use my phones flashlight to do it). Oddly enough, being colourblind has made me better than my coworkers at wiring up Cat6, as I double and triple check each of my connectors quite thoroughly to make sure there is no mistakes (As me making a mistake will directly be blamed on colourblindness and my abilities will be called into question, if a coworker makes a mistake it is just that - a mistake).

A friend of mine discovered his color blindness when he joined the military and took an eye exam. He said he never noticed things like stoplights red/green being very similar because he just thought that was how it is supposed to be.
