I knew I was colour blind to certain shades of green since my early teens (I’m now 38). I had one of those colour blind tests with the coloured dots showing numbers and lines. One particular pattern I couldn’t see, the practitioner said just run your finger on the line you see, I squiggled all over the dots. I heard my dad saying to the family that night that the line went straight across.
It has never phased me, I have never noticed it, I haven’t been aware of it in anyway…. until last night.
On my bedside draw sits a clock with luminous red digits, a swm v10r with ice blue trits (I should mention at this point in time the v10r was on the floor not 400mm away from the draw) and a kind of a lamp (see picture).
It is actually a 3D puzzle of a Japanese building called ‘Sky Tree’. The base has three coloured led’s and as you can imagine it mixes the light to make numerous colours as well as cycling through colours.
Anyway, to get to the point of this post, I had it on green last night. It has always looked green to me (as far as I’m aware). I turned it on and the main room light went out. I didn’t immediately turn it off, it was on for a short time. I didn’t pay any attention to the light until I went to turn it off. I said “That’s funny. I thought it was green before”. My wife says “What are you talking about? It is green.” It was no shock to me, I immediately knew what was going on. I looked carefully at the light as this was the first time in my life I got to ponder on my colour blindness. I described it to my wife as yellow with a hint of green and orange. I turned the room light on and it instantly looked the brilliant green that it was before.
It made me wonder if I am really able to see if an led turns the ugly green. I am generally aware of the different colour temps of the lights I have and have even noticed very light green tints before. But now I wonder if I am really seeing it for the true colour it is.
Is anyone else colour blind? Are you aware if it affects your flashlight addiction? Is there some kind of experiments or something I can do to explore the limits of my blindness?
I had a friend that couldn’t see green and in some town’s they put the traffic lights in different orientation than standard up and down with red on top. He got stopped for running a red light, reds and greens appeared the same to him and he realized he’d been using the fact that a light was lit on top or bottom for years, not distinguishing if it was red or not. The cop could care less, but noted on the ticket my buddy was from out of town. My friend took it to court in the small town and showed the judge that the towns oddly placed lights were confusing and got the ticket dismissed.
Men are more usually color blind than women, and a great many men have at least some issue if that means anything to you. I guess whatever shades I’m weak in aren’t green, as a de-domed XM-L2 can be very ugly to me and a true pita when you drop $40 on 4 emitters for a Terminator only to hate the color! (fixed that with 4 new domed U2 1D’s)
Ask your optometrist to test you again so you’ll know what shades are your trouble zones. Have him/her clearly identify the shades so you know what they look like to you and you’ll be able to know that a dingy yellow is actually bright green or whatever.
I’ve been thinking about this for quite some time.
For the most part when I show people my flashlights people actually prefer the warmer or neutral tints when I show them the difference. But then I have this friend that always, no mater how ugly I find the cool white of that certain flashlight to be, prefers that one when compared to a neutral flashlight. Always. The thing is that this friend is colour blind, I don’t know which colour he has problem with, which have made wondering if there might be something that affects which kind of tint you prefer.
Might I ask if you prefer warm, neutral or cool tints?
aoeu, this is the first time I have had a chance to look into it (pun?? H) ) so I don’t know what other shades look like in comparison.
Good advice DBCstm, thanks. I’ve never had a problem seeing traffic lights. :nerd_face:
Volk, my tint preferences depend on the if the light is flood or throw. Flood I like around 4000k-4500k, throw 4500k-6000k. I don’t especially ‘like’ the 6000k tint but I feel I can see clearer with the cooler tints at distance.
The thing I find curious is I was blind to the green when it was the only light in the room. When the main light came on I could see the green easily.
I have similar colour blindness.
Also in the green/ yellow area…
The dots I can’t make out either.
But that is more like a colour contrast problem.
It’s very common for men to have some colourblindness.
0 ( Perfect Color Acuity ). :~ Didn’t think it would be perfect because I did not feel like I tried that hard to compare color squares. Very slight difference between each.
Maybe I should purposely mix 2 squares just to check that the test doesn’t ignore if your very slightly off.
Yea mixing 2 squares will change your score, definitely! 0 is a great score. I tried pretty hard to get a 3. Sometimes I could see something wrong but didn’t know what so I just left it.
And in this age your monitor will easily display the different hues but perhaps our eyes can’t pickup the subtle differences.
Similar problem here, I found about it when I had my eye examination for driving licence
long time ago but I never experienced or noticed strange color mismatching in real life! It all looks normal to me :bigsmile:
My father is color blind. My mother researched whether it would be passed to children, while they were still just dating. This was before the internet, when it took effort to find good information.
Guys, it is fun but take it with a grain of salt your displays’ gamut is most certainly UNable to properly show the differences, plus ambient luminance and screen luminance aren’t take into account. I did it for the fun and got a 3 too, with a proper display (with larger gamut and better color precision) in a dimly lit room my score could be different.
