--- Quote ---The reason for the blue/brown is due to some common colour blindness seeing red and black as the same colour.

Another example of snowflakes interfering. A  colour blindness test used to be part of the interview prosess before being offered an apprenticeship  ,fail it  and  your out.But of course failures not allowed anymore.

10% of men are red-green colourblind.  It's not a small amount of people to reject.

I doubt that has anything to do with it. The idea that true colourblindess is common amongst men is a largely myth. The type of colourblindness which would make it impossible for someone to distinguish red and black, or even red and green is comparatively rare.

Colourblindness is a misnomer. It's true 10% of men fail the colourbliness tests, but that doesn't mean they see the world in greyscale. It's more subtle than that. The most common form of colourbliness is deuteranomaly which is very mild and often given the name red-green colour blindness, but it's not that simple. Most people with deuteranomaly can still distinguish between red and green.

Deuteranomaly is simply an anomaly in the green pigment in the cones of the retina, which shifts their response towards the red end of the spectrum, making it more difficult for someone with this condition to distinguish between some hues in the red-green end of the spectrum. This isn't a problem with bright colours: theey will still be able to tell the difference between fully saturated red, green, orange and yellow, but darker shades can be more challenging to differentiate.

Like many men I have deuteranomaly, but I can still use the resistor colour code in well lit conditions. It's only a problem when it's a bit dark or the paint is poor quality. Some cheap resistors use a dark red paint, which often looks like brown and the yellow often looks like green on blue resistors.

If an optician tells me I'm red-green colourblind, I correct them by telling them I'm brown colourblind. If they don't believe me, I prove to them I have no problem distinguishing between red and green objects, but might struggle with dark red and different shades of brown. Obliviously being brown colourblind means I can't be racist.   ;)

Really? Back in the days of colour banded resistors I used to get a LOT of resistors stuck under my nose by some random guy at the next bench, asking me to read them. If it was possible for them to distinguish the relevant colours to some extent, their ability certainly wasn't good enough to give them any confidence.

I would hate to be colorblind. I've always had excellent vision and find lights and bright colors to be very visually stimulating. I've looked at simulations of various forms of colorblindness and was shocked at how dull and drab the world looks.

Actually that makes me wonder if there's any correlation between colorblindness and forms of depression. Drab bland landscapes make me feel gloomy, bright colors make me feel good.

I don't disagree with him, although I do think that racism is not as common as many think, at least a lot of things that people blame on racism are not. It's one of those things though where if you believe everyone is racist then you're going to see racism everywhere you look whether it is there or not, it's a form of confirmation bias. A great many people project their own racism on everyone else too.

Regarding that word, given how broadly offensive it is to many people it seems better if nobody uses it, at least not in the context of referring to another person. If the black community wants to have it as their word, fine, who am I to tell them not to say it, but as long as people keep saying it, it's going to stay in the vocabulary. As with all these other words that have been discussed though, it's not actually the word itself that's the problem, but the message it is used to carry.
Simon:
That was my point it's how the word is used and in itself is not offensive but then that is the exact same position we find ourselves in with master/slave while not offensive they are now deemed offensive by some people who want to say they brought about change and solved racism but telling other people what to do.
