Reference the article primary colors at it's first appearance in the article

Change: Similarly, most human color perceptions can be generated by a mixture of three colors called primaries. This is used to reproduce color scenes in photography, printing, television, and other media. There are a number of methods or color spaces for specifying a color in terms of three particular primary colors. Each method has its advantages and disadvantages depending on the particular application.

Maybe a variation of the Munsell system would be a more elegant way to create each "shades of x" article

I started out thinking that the RGB system was the way to go, but I soon noticed its shortcomings. One of them is that its colour wheel is not balanced. For example, the transition from red to yellow is way too short in the wheel. After seeing many different colour wheels, I believe that Munsell's is the most balanced when it comes to doing justice to each hue's space in the colour wheel, and not overemphasising others. It makes the most sense while looking at the spectral colours in firsthand through a prism. It also has the property that each one of these hues is really close to its complementary. Please let me know what you think.

Example of how it would look like (for the hues only, it excludes brown or pink, for example):

1 Shades of red

2 Shades of orange

3 Shades of yellow

4 Shades of chartreuse/lime (main representative colour being near #98cf00)

5 Shades of green (main representative colour being near #19d451)

6 Shades of cyan/aqua (near #00c7b0)

7 Shades of blue (near #1f9bed)

8 Shades of ultramarine/indigo (near #6369ff)

9 Shades of purple/violet (near #bf66ff)

0 Shades of magenta (near #ff57b3)

You can also notice that these colours match their complementaries really well:

red-cyan

orange-blue

yellow-ultramarine (it's the same hue as the RGB 0000FF)

chartreuse-purple/violet

green-magenta

The RGB red is slightly orange-ish. If you look at the red through a prism, you can clearly see that there is a redder red than the RGB one. If we try to find the complementary for this pure red, it falls somewhere between 170 to 180 degrees in the HSV hue wheel.

I also think that the archetypical blue should be something around 210 degrees, because that's what most people and cultures think of the archetypical blue. The RGB blue is slightly violet-ish.

So my proposal is to: 1 merge 'shades of cyan' and 'shades of spring green' and call it 'shades of blue-green'.

2 rename 'shades of azure' as 'shades of blue' and add some new colours to it that represent both the blues closer to cyan and the blues closer to ultramarine.

3 rename 'shades of blue' as 'shades of ultramarine or indigo', and move some of the colours there to the new 'shades of blue'.

4 merge 'shades of magenta' with 'shades of rose'.

Take a look at ISCC–NBS system. –jacobolus (t) 09:35, 14 April 2023 (UTC)

In my opinion, I think it's missing blue-green, magenta (those hues between 300 and 350 degrees), and ultramarine (between 230 and 255 degrees) as primary hues. In my opinion, these hue areas deserve acknowledgement on par with 'shades of red' and so on. Restfultree2022 (talk) 22:01, 14 April 2023 (UTC)

These are all given clear and unambiguous names. "Magenta" is called purplish red (pR), "ultramarine" is called purplish blue (pB). Also "teal"/"turquoise" is split into bluish green (bG) and greenish blue (gB) (though personally I might instead make a single blue–green category a bit smaller than the combination of those two put together). The point was to make precisely defined categories, not to give every category a one-word name. Anyway, this is more or less what you were asking or: a clearly specified system based on Munsell coordinates. –jacobolus (t) 23:06, 14 April 2023 (UTC)

I see. Yeah, what I'm mostly pondering on is what the exemplary colour code should be for the archetype of each hue.

It's also about the balance of the colour wheel. I see more difference between red to yellow than red to RGB magenta for example. The RGB green is slightly yellower than the greenest green I can see in the spectrum. The RGB colour wheel gets quite strange around green. One it gets near 120 degrees, there is very minimum difference. That's not what happens in the rainbow. I think it has something to do with how limited the sRGB gamut is about making those greens.

I'm thinking, maybe this is the most balanced way to divide the colour wheel: https://imgur.com/a/hOYTYFJ

But I'm not sure. Restfultree2022 (talk) 02:34, 15 April 2023 (UTC)

Ungrammatical

The second sentence in the section "Colors of objects" is this:

"Most objects scatters light to some degree and do not reflect or transmit light specularly like glasses or mirrors."

This page is protected but doesn't display any corresponding icon or banner, which I found a bit confusing... {{pp-semi-indef}}, I think?
