What is Color Blind – Simulating Vanilla Shaders Pack?

This pack was created as a way of educating resource pack artists about color blindness, and the effects that their color choices have on a particular section of the human population. With the publication of this pack, he hope to raise awareness of Color Vision Deficiency in all its forms. He also hope that it will help to promote good design choices, both for resource packs and for design in general, that takes into account CVD and other ease of access measures.
He hope that this pack allows people with normal vision to walk a mile in the shoes of someone living with CVD… even if only for a few minutes in a video game.
IMPORTANT: No actual textures are included in this pack. This is a set of shaders programs used by vanilla Minecraft for it’s Super Secret Settings. It can be used with absolutely any other texture pack without issue, and without any required mods.

All information presented below is heavily abridged and phrased in a way that’s hopefully simple to understand. I make absolutely no guarantee that it is 100% accurate, and as such you should use this information as a jumping-off point for your own research rather than simply believing what I’ve typed outright. If you find a serious mistake in the information presented below, please tell me. While I don’t make any guarantee that I’m going to get the information right, I will at leasttry to make it as accurate as I can in it’s abridged form.

In a normal human, color vision is possible because of the three types of cone cells in our eyes. Each one percieves a fairly wide spectrum of light, roughly corresponding to the colors red, green, and blue. These three base colors of light mix together to create all of the beautiful hues and shades that most humans take for granted as being things that people see.

Before you think that humans have the best vision of all animals, though, take a look at the vision of butterflies. These creatures are tetrachromats, and can see ultraviolet light. If you really want to have your visual perception humbled, try standing next to the amazing Mantis Shrimp which has a whopping twelve different color receptors, putting our wimpy three receptors to shame. A normal human is colorblind in comparison to either of these fascinating creatures.

Deuteranomaly is the most common form of color deficiency there is. Like most forms of color vision deficient, it affects males more than females due to it being a sex-linked trait. Deuteronomy is characterized by the middle-wavelength (green) of the color spectrum to be shifted more towards the red end of the spectrum.

People with this type of color vision can still see green, it just looks very yellow to them. By the same token, the red end of the spectrum becomes diluted with green, causing it to move towards orange and yellow as well. For this reason, Deuteronomy is sometimes referred to as “mild red-green colorblindness” since it presents similar challenges to those with Protanopia and Deuteranopia, the two forms of true red-green colorblindness.

While only about 6% of the male population has Deuteronomy severe enough to qualify as colorblindness, some experts say that a significant portion of men a very mind version of this. If you’ve ever been told you’re not calling a color the right name, particularly if you’re male, you might want to try an Online Color Test to make sure you’re seeing what everyone else is seeing.

Deuteranopia, also called Daltonism after physicist John Dalton, is the most common type of red-green colorblindness. It is caused by an absence of the absence of the M cone in the eye, and thus the loss of ability to view Medium wavelength colors.

People with Deutranopia have trouble distinguishing shades of red, orange, yellow, and green. With the absence of the ability to see green, red simply fades into a variety of orange hues and cyan takes the place of some of the greens. Shades of blue are unaffected, except where they mix with red to make purple, which also can’t be seen with this type of color vision deficiency.

Protanomaly is similar to Deutranomaly in that it’s not a true form of “colorblindness”, but in fact an issue with how colors are perceived. People with this type of color vision deficiency still see the color red, but perceive it as being orange due to a problem with the S cones in their eyes moving the Short end of the visible spectrum closer to green. Someone who can’t tell the difference between red and orange, but gets the rest of the colors right, may have this disorder.

Protanopia is very similar to the other form of red-green color blindness, Deuteranopia. In fact the two are so similar that most people don’t even make a distinction. There is one key difference, however: With Protanopia the Red end of the spectrum appears very dark, even to the point of appearing nearly black. This can be seen in the screenshot above where the bright red poppies appear to be a very dark shade of yellow approaching black.

Most commonly called “Blue-Yellow colorblindness”, this is actually inaccurate to what’s actually happening. Those with tritanopia lack the L-cones in their eyes, and thus don’t have the ability to see blue light. The M-cone, green light reception, fills in a lot of that gap making the entirely of the green-cyan-blue spectrum appear in cyan while yellow is dropped almost completely into white. Red can still be viewed reliably, but without any blue spectrum to mix purple and violet just becomes pure red.

Tritanomaly is the blue-shifted cousin of the other two -omaly disorders. Like Protanomaly and Deuteranomaly, Tritanomaly shifts the high point of color perception towards a point somewhere between the Low and Medium frequencies of color. In other words, more towards green.

Those with this type of color vision deficiency see everything shifted slightly towards the lower end of the spectrum. Yellows become more orange, and oranges become more red. True greens become yellowed while most of the green spectrum becomes more cyan. This change makes it difficult to distinguish colors on both the high and low ends of the spectrum, while making the middle somewhat confusing.

When most people think of colorblindness, this is what they think of. This is unfortunate because complete colorblindness (monochrome vision) is one of the rarest forms of colorblindness there is.

When a person is achromatic, they have only a single type of cone in their eyes (or none at all) so they effectively see only a single color. This means that there are effectively three types of achromatopsia: L-only, M-only, and H-only. Each one appears different with the colors corresponding to the cone that they have appearing somewhat brighter than the rest of the spectrum.

There is also an extremely rare form of achromatopsia in which a person is born with no cones at all, relying entirely on the rods in the eyes for vision. That is, only the person’s night vision. Affecting less that a thousand people worldwide, this type of vision deficiency makes normal light unbearably bright and severely limits the ability of the individual to see details.

Due to the rarity of these conditions the information regarding how people with these conditions see the world is severely lacking. This resource pack doesn’t have an accurate filter for any of these as a result. Instead, this pack effectively using an advanced grayscale filter that uses a normal eye’s sensitivity to colors as the basis for how it responds to color. If you have any information on exactly how people with any form of achromatopsia see the world, please post in this thread. I’d love to add accurate filters to this pack for every form of color vision deficiency.

The rarest form of color vision deficiency, this rare case is most commonly a transitional stage between normal vision and Achromatopsia where in that condition is brought about by a chemical change in the person’s eyes or brain rather than a genetic condition. Achromatomally (reduced color vision) is most often brought on with the onset of Macular Degeneratonstemming from either aging or diabetus. It’s also been linked to brain damage, drug abuse, and other rare non-genetic causes of color vision deficiency.

How to use Color Blind Resource Pack

Each type of Color Vision Deficiency has been assigned a number roughly equating to how common it is in the human population. Zero, normal vision, is the most common. Consult the images in the spoiler below to see the number associated with a particular spectrum of vision. To return to toggle between normal vision and a colorblind state once one has been selected, use the F4 key.

  3. thank you very much

  4. lick me

  5. why optifine version is not compadible with the super secret setting

  6. ah i think this is color blind mode
