I guess the question is, are the four cones in a tetrachromatic eye at the same frequencies as in a trichromtic eye, plus one extra, or are they at different frequencies?

The former, from everything I've read/watched. So you'd still have the three cones being targeted by RGB, and a fourth cone that falls between two of them.

I know that the brain is perfectly well aware of the difference between mixed frequency light and a single pure frequency, otherwise the colour magenta would not exist - to create magenta, the brain takes a mixture of red and blue and, instead of averaging as it would usually do (which would give green), instead interprets it as a completely different colour that doesn't actually exist as a pure frequency. So the processing that's going on when seeing the colours on a monitor is super complex.

It's not as hard to model as you might think.

Our understanding of which colors are "primary" in light and pigment are directly related to the cones we have. The concept of primary colors doesn't exist as a function of the wavelengths of light, it exists as a function of our reception of color and resulting processing.

Magenta works as a secondary color because we do have receptors for Green as a primary color, and thus recognize its absence, and extrapolate Magenta accordingly. Red and Blue with Green present doesn't get you Green, it gets you White. Green alone is not the averaging of Red and Blue, it's the direct reception of Green. That's how Red, Green, and Blue are the primary colors of light.

The secondary colors and below are averages of varying amounts of Red, Green, and Blue, and we're pretty clear on how because we've been using Red, Green, and Blue lights to generate the full rainbow for far longer than we've had colored LEDs - additive and subtractive color theory is essential for theatre tech.

But now anybody can play with it, because we can see how a set of RGB LEDs themselves stay their own colors, and how the resulting light on other surfaces is the selected blended color.

This is why I don't see how a fourth cone is going to help distinguish more detail in digital color, and possibly not in CMYK ink either, given that they work by layering pigments in primary colors to get secondary colors.

But traditional pigments, color in nature where what's being reflected is the specific wavelengths of that color, rather than sets of other wavelengths for our brains to average/blend? Yeah, that makes sense. That's exactly why other animals do have other cone sets.

25% of the people have a 4th cone and see colors as they are

Given the sudden interest for the color of dresses and vision, here some of the fascinating findings we did recently.

The color nuances we see depend on the number and distribution of cones (=color receptors) in our eye. You can check this rainbow: how many color nuances do you count?

You see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat.

You see between 20 and 32 color nuances: you are a trichromat, you have 3 types of cones (in the purple/blue, green and red area). You enjoy different colors as you can appreciate them. 50% of the population is trichromat.

You see between 33 and 39 colors: you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). You are irritated by yellow, so this color will be nowhere to be found in your wardrobe. 25% of the population is tetrachromat.

You see more than 39 color nuances: come on, you are making up things! there are only 39 different colors in the test and probably only 35 are properly translated by your computer screen anyway :)

It is highly probable that people who have an additional 4th cone do not get tricked by blue/black or white/gold dresses, no matter the background light ;)

The true botw shrine experience. I don't think Four approves!

The full comic page and some colorful Fours can be found under the read more!

A meme redraw based on something I did in a playthrough lol. Out of arrows? Throw your sword!

I love Four so much aaAA

This didn't turn out the way I wanted it to but. Had this idea in my head far too long I needed to get it out

These two have such a funny vibe, had to take Zelda out of half their games because you know she’d just be telepathically negging him the whole time. Theyre besties, theyre potentially related, she’s mentally whispering ‘Sandwich’ in his ear whenever he’s trying to focus.

Edit: Added funny page in celebration of me not having to rework these designs for the new game

Although Fairies appear humanoid in nature, they actually have a more pure form unseen by the naked eye. This is because Humans lack the ability to perceive anything beyond the fourth dimension. Given enough magic, a Fairy can manifest their true form onto all planes of existence.

This is usually not recommended, as seeing a Fairy's purest form can cause madness. A Fairy should only use their pure form when necessary, such as containing uncontrollable wishes, or high quantities of magic. Especially since there's heavy drawbacks and sacrifices to manifesting one's pure form.

Two blokes slacking off at work :p

Cretan diplomats based on a painting of the tomb of Rekhmire, Luxor. I was intruigued by the leopard skirt thingy one of them is wearing and drew a more or less realistic interpretation of it! The other guy's there so he can have a buddy.

While i usually draw people looking as average as possible, it's not the case here. It's fair to assume that within the "PR" context of the painting (representing their people in front of a foreign king) these would be the ancient aegean's hottest boytoys, so I kept them snatched and smooth shaved.

Originals under the cut!

guess who got around to making refs and definitely did not put off making them for a year!!!!!
