By what method would you suggest calibrating one's monitor? I use Debian Linux if that's a factor.

You can do it on Linux but you need to buy a device you attach to your monitor. I have a Spyder X Pro but there are others. It’s like $200 and it’s not worth it unless you do color sensitive work (photo editing, printing or video editing) and you have an expensive monitor or expensive laptop with good color support. Many monitors will fail so badly the calibration won’t be able to fix it. But if you’ve ever had a lot…

Thank you.

I wonder if photo stores might have the device, and if they would loan it. I'm surprised there is no method of calibration against common objects of known colour, such as Euro bills.

I had a colour-blindness test when I worked at an abattoir.

My job was to find odd things on a one third section of a side of beef as it went past and cut it off. 1500 or so per day.

The test showed numbers created with blobs of close colours.

The last test didn't have a number in it.

Cheeky buggers.

Dunno if this is a late-in-life thing or I was always like this, but I definitely need more blue to see blue than most (this test put me at 82%, I think that means I'm in the lowest quintile for seeing blue?) Bright blue still looks mighty blue, but when light is dim, I basically see black where most would still see blue. Practical ramifications: * Some of my 'black' shirts are blue when it's sunny * Popular desktop…

I remember a pic of a shirt, which a former colleague of mine was showing on his monitor ten years ago, and the office splitted half in recognizing the colours, can't remember if they were gold vs black; but we went crazy because nobody could believe that the other half was seeing a colour different from the one they were seeing!

As other commenters here have noted, I found this interesting but a little frustrating. The second color it asks about is clearly cyan (or turquoise). For me, this is like showing an orange screen and asking if it is red or yellow. I understand that across cultures "orange" does not exist as a distinctly named color (it only got its name in most European languages around the 1500s), but as someone who was trained sin…

Tried this on 2 monitors, made a difference of 77%-85%

I noticed that what I was actually seeing later on was 'is this more blue or green than the last colour' due to my eyes adjusting to the previous screen and just seeing the difference.

The current use of "cyan" for blue-green is a modern confusion caused by people who have used Greek words without bothering to check their true meaning. In Ancient Greek, "cyan" was blue, not blue-green. More precisely, it was the color of the pigment "ultramarine blue", which has remained widely used until today. The name of this pigment was already used by the Hittites, long before the Greeks. An example of a Latin…

Someone has downvoted this, despite the fact that what I have written is not an opinion, but just facts. Because I have seen on HN extremely frequently downvotes that just show that the downvoters are ignorant about what they downvote. I stopped a long time ago to downvote comments. Now I either upvote when I agree and otherwise I write a comment explaining why I disagree. It would have been better if others had foll…

It is not an incorrect meaning, it is that meaning of the word in English is different. What it meant in ancient Greek or in 1805 is not relevant to what it means today.

Words meanings shift over time in all languages. And when languages take sounds from other languages, they also regularly shift their meanings.

BTW, cyan is very poorly represented by sRGB color space. I was delighted to see the real vibrant cyan of the Mediterranean sea.

That went from a fun, interesting experience, to wondering if this is how SCP 3125 was going to get me, as the entire screen seemed to become a wild glowing green long after the animation likely ended.
