: List of RGB quaternary (and beyond) colors? I'm trying to organize a list of colors for a puzzle game. I can find reliable lists (names and colors values) of the primary, secondary, and tertiary

@Mendez620

This is a mixture of common names and my own inventions (in cases where there are no common names).

Quaternaries in roman, tertiaries in italics, secondaries in bold, primaries in both

Reds:


Red - #ff0000
Vermilion - #ff4000


Oranges:


Orange - #ff8000
Amber - #ffc000


Yellows:


Yellow - #ffff00
Neon Yellow - #c0ff00


Greens:


Chartreuse - #80ff00
Bright Green - #40ff00
Green - #00ff00
Irish Green - #00ff40
Spring Green - #00ff80


Cyans:


Turquoise - #00ffc0
Cyan - #00ffff
Sky Blue - #00c0ff


Blues:


Azure - #0080ff
Cerulean - #0040ff
Blue - #0000ff
Indigo - #4000ff


Purples:


Violet - #8000ff
Purple - #c000ff
Fuchsia - #ff00ff


Pinks:


Magenta - #ff00c0
Rose - #ff0080
Crimson - #ff0040

My 2 cents.

1) There are no standard list of names of colors. The link allcaps provided in the comment is a funny explanation why. blog.xkcd.com/2010/05/03/color-survey-results/
2) If you want a "standard" list of RGB colors, one possible reference is the w3 list of extended color names: www.w3.org/TR/css3-color/#svg-color
3) The concept of tertiary and quaternary is only related of a painting process, where you needed a methodology to reconstruct a specific color in a progressive way.

In RGB mode you do not construct a color mixing equal parts of a primary color, and then mixing it with another part of a primary color etc. You just assign values, so the concept does not work here. You can not find such a list, because I doubt anyone really needs it or has made it. Probably it is a fun exercise.

4) But, based on a standard color name list like the one I provided, and making your own calculations you could measure the RGB values and choose what color name is approximate of the values. It needs some work but can be achieved in a couple of hours.

I used the list of RYB quaternary colours at en.wikipedia.org/wiki/Tertiary_color#Tertiary-_and_quaternary-color_terms to fill in some of the gaps between the CMY tertiary colours.

I've listed the CMY tertiary colours from that article and indented proposed names for the quaternary colours.


Red


Crimson (or Russet)

Rose


Aubergine

Magenta


Amethyst

Violet


Indigo

Blue


(Cerulean)

Azure


(Celeste)

Cyan


(Aquamarine)

Spring green


(Emerald)

Green


Apple green

Chartreuse


(Citron)

Yellow


Amber

Orange


Vermilion

Red


I got these names by translating the CMY colour names into RYB equivalents and then looking for the names of intermediate CMY colours. I used the following equivalencies


CMY - RYB - (CMY colours mixed)
Magenta - Purple (blue - red)
Rose - Magenta (red - magenta)
Violet - Violet (magenta - blue)
Cyan - Teal (blue - green)
Azure - Turquoise (blue - cyan)
Spring green - Viridian (cyan - green)


The CMY colour will be more saturated than the RYB equivalent.

Citron is a tertiary colour, a combination of green and orange, which lands between yellow and chartreuse on the colour wheel. (https://en.wikipedia.org/wiki/File:RBG_color_wheel.svg) Likewise, russet (orange and RYB purple, or orange and CMY magenta), coincides with crimson, half-way between rose and red.

I couldn't get the quaternary colours from blue to green from that page, so the suggestions above are just for completeness.

How "official" do the colour names need to be exactly?

The first thing I thought of was looking at colour names given to paint by companies such as Dulux they use names for a whole range of shades and tones.

What lies beyond primary and secondary colors?

Tertiary colors are created by combining adjacent primary and secondary colors. For example with the traditional primary and secondary colors our tertiary colors would be vermilion (red + orange), amber (yellow + orange), chartreuse (yellow + green), teal (blue + green), violet (blue + purple), and magenta (red + purple). Note, this magenta is not quite the same as that found in the CMY color set.

The tertiary colors for the RGB and CMY sets are azure (cyan + blue), violet (blue + magenta), rose (magenta + red), orange (red + yellow), chartreuse (yellow + green), and spring green (green + cyan).

Another group of tertiary colors can be created by mixing secondary colors: the quaternary colors, the names for the twelve quaternary colors are more variable, if they exist at all, though indigo and scarlet are standard for blue–violet and red–vermilion.

From the mix of the previous colors we get quinary colors, which are, roughly, varying shades of gray, this is way there are no specific names beyond the tertiary colors. The more you mix the colors the harder it is for the human eye to detect those differences.
