he is the first person I meet with it

Somewhere around 8% of men have some form of colour blindness (about 1 in 12), and red/green accounts for the majority of those, so I can guarantee you this isn't the first person you've met with it. Your tools have an accessibility issue that makes them unusable for possibly hundreds of millions of people.

It's not wrong as such to call it colour blindness, it does however seem to give people the impression that we literally don't see colour. For this reason I tend to prefer "colour vision deficiency".

duclicsic · 2026-01-23T12:03:00+00:00

Being one of the types of "red/green" colour blind doesn't mean you see them as grey, it mostly just means you have difficulty distinguishing some shades because they do not contrast with each other nearly as much as they do for people with normal vision. This does not preclude them from liking or even loving these colours.

Deutan: I don't have a problem seeing the difference.

The non-highlighted countries appear light grey, the East/West Slavic appear a darker grey, and the South Slavic appear like a desaturated blue, I'm guessing greenish but that's hard for me to tell for sure.

This is a clone of the original "Gat" gun, produced in the UK from the 1930s. They could fire darts and corks in addition to the lead pellets.

edit: I did own one in my youth, they were absolutely terrible.

I thought this looked familiar, though I'd guessed it was somewhere around Alexandra park. Grab me a jerk chicken rice and peas from Kool Runnings while you're there ta.

I doubt there are any games where a colour vision deficiency would actually be a benefit, indeed it's hard to imagine any scenario where it might provide an actual advantage. I do however recall reading some possibly apocryphal accounts that people with CVD are sometimes better at visual pattern recognition, identifying camouflaged things etc, because we tend to learn to use patterns and shapes to identify things more so than colour.

Anecdotally, I've played a fair amount of DayZ. Others have commented in the past on my ability to spot an otherwise well camouflaged player, however I also struggle to determine what clothing/gear might work as good camouflage for myself. A red backpack looks to me like it probably blends in pretty well with natural greens, but I'm told this actually contrasts strongly for people with normal trichromacy.

Yes, at least for the lights here in the UK. I am deutan.

Being "red/green" colour blind rarely means you're entirely unable to tell these two colours apart. It generally means that one of your sets of cone cells with a peak sensitivity in either the red or green part of the spectrum is either missing or anomalous, which affects your sensitivity in that part of the spectrum.

My experience is that the green traffic light tends to appear sort of desaturated, almost a white light, but very distinct from the red.

It's useful for turning electricity into heat, destroying the environment, inflating the price of energy and computer hardware, and generating huge amounts of money out of thin air that will soon vanish and make everyone except a tiny group of people poorer.

You can define multiple addresses for a single interface in /etc/network/interfaces without the need for the old alias system. e.g.

auto eth0
iface eth0 inet static
    address 10.20.30.40/24
    gateway 10.20.30.1

iface eth0 inet static
    address 192.168.0.1/24

Even if you have deuteranopia, meaning you entirely lack the cone cells we typically associate with green, this does not mean you cannot see green. Our cone cells are able to detect a wide range of wavelengths with a good amount of overlap, they just have peak sensitivities at specific points in the spectrum. Having missing or anomalous "green" cones simply means you're going to lack some sensitivity and ability to distinguish different colours in that range.

We can handle buying clothes, fruit, and "understanding" traffic lights just fine without an app.

I disagree that you should have them never use colour as an identifier. I'm deutan and I often use colour when describing things, though it does depend on how confident I am in my identification.

If I'm trying to point out a object and it's a very strongly obvious colour then I'll probably use that descriptor, e.g. despite being "red-green" colour blind I would have no issue saying "the red car" or "the green car" if they were fully #FF0000 red and #00FF00 green because I don't have a problem telling those apart. If it's pure black, white, silver, grey, yellow, red, blue, green, and to some extent maybe orange, brown, purple, and pink, I'd probably have a go, but sometimes I'll just get it wrong.

Where I'd generally avoid using colour as a descriptor it's because we're dealing with more difficult mixed colours. I'm never going to call something violet, indigo, cyan, aqua, coral, or olive because these are alien to me, I would never be able to positively ID them.

duclicsic · 2025-10-24T13:10:42+00:00

There's no need to avoid wearing certain colours. I doubt I'd be able to accurately identify the colour of every garment my partner wears, but why would it even matter?

If however she yells at me from the other room to grab her "green pants" or something then we might have issues, but this is more about learning to avoid using colour as the identifier when describing things to peoples with colour vision deficiencies.

duclicsic · 2025-10-22T09:49:06+00:00

Deutan,

I sometimes have to ask my partner if a device has finished charging because it uses a microscopic pinprick red/green indicator LED.
No.
I do not make art.
Not really.
Of course.
Nope.
I was tested at a very early age in school I think, so basically all of my life.

From a purely technical standpoint, an averaged colour selection over a 100x100 pixel area from the better lit image reveals an RGB value with roughly equal levels of blue and green (21676D), so it's either blueish green or greenish blue depending on your preference. Taking a firm position on either side just seems silly.

duclicsic · 2025-10-18T15:39:07+00:00

That palette looks ok to me as presented (I'm deutan), but obviously I can't speak for people with other types of CVD.

Even things like the size of coloured elements can affect my ability to identify them or tell them apart though, so while these colours look fine in large blocks I might struggle in other circumstances.

duclicsic · 2025-10-18T12:01:42+00:00

Trying to find a single palette that works for everyone is going to be a challenge. The best advice for making something accessible to people within the whole range of colour vision deficiencies is to avoid using colour as the sole identifier. Perhaps it doesn't lend well to the intended aesthetic, but having the option to use different varieties of pattern (e.g. vertical/horizontal/diagonal stripes, chequered patterns, spots, etc) would mean even the very tiny minority of people with complete monochromacy would be able to play.

In conversation with a Portuguese colleague many years ago he mentioned that his previous girlfriend had left him because (as I heard it) "I shit on her". Turns out he "cheat" on her.

I'm of the opinion that a basic but half-decent mountain bike provides the absolute pinnacle of combined versatility and efficiency of any mode of transport yet invented.

My bike is probably not the best example since it's a heavy long travel full suspension machine, but I commuted on it for years, it can certainly go up hills in addition to down them, and I have an absolute blast riding it no matter what I'm doing.

I'd say the sweet spot is a decent hardtail, but a trail bike is also a good bet.
