A very common problem is that purple colors look more like blue. Another common issue is that pink colors appear to be gray, especially if the pink is a more reddish pink or salmon color. Another symptom specific to Protan color vision deficiency is that red colors look darker than normal.
Tritanomaly makes it hard to tell the difference between blue and green, and between yellow and red. Tritanopia makes you unable to tell the difference between blue and green, purple and red, and yellow and pink.
Pink is the velvety tenderness of a rose, a flamingo feather slithering between your fingers – a wildchild who unabashedly, viscerally lives so. Pink is the warmth, the blush on your cheek when you think of your beloved in her/his absence.
For example, blue/orange is a common colorblind-friendly palette. Blue/red or blue/brown would also work. For the most common conditions of CVD, all of these work well, since blue would generally look blue to someone with CVD.
Another task that can be frustrating is driving a car when color blind; for the color blind person, green light tends to look very pale green or nearly white, and red light may seem closer to orange.
That being said, here's a few color combinations to avoid because they're a potential nightmare to color blind users: Green & Red. Green & Brown. Blue & Purple.
Use a colour-blind-friendly palette when appropriate
For example, blue/orange is a common colour-blind-friendly palette. Blue/red or blue/brown would also work. For the most common conditions of CVD, all of these work well, since blue would generally look blue to someone with CVD.
There are different types of colour blindness and in extremely rare cases people are unable to see any colour at all, but most colour blind people are unable to fully 'see' red, green or blue light.
People with reduced blue sensitivity have difficulty identifying differences between blue and yellow, violet and red and blue and green. To people with blue deficiencies the world appears as generally red, pink, black, white, grey and turquoise.
The rest can be appreciated through touch: the cluster of petals on top that feel like a bulb of silky skin; the stem is thin and straight, riddled with sharp thorns; a couple of branches come out of the stem and lead to leaves, which are flat, plus rough on the bottom and soft on the top.
Pink is a nurturing, playful, and nostalgic color that takes people back to their childhoods. That said, pink is a color of opposites since it can make us think of both innocence and burning passion. Bright and hot pinks are associated with love, romance, and even lust. Intense pinks create a sense of urgency.
Let blind people touch something that is related with a certain color. You need to use things that usually have the similar color at one time. This way it will be easy for a blind person to relate certain materials or feelings to a color.
It's not a name we give to something out there. Pink isn't out there. True, no single wavelength of light appears pink. Pink requires a mixture of red and purple light—colors from opposite ends of the visible spectrum.
Tritanomaly—faulty blue cone. This condition is the least common form of color vision deficiency. Individuals with tritanomaly see the world in shades of pink (standing in for orange, yellow, and red) and turquoise (standing in for blue, green, and violet).
Erythropsia or red vision (from the Greek erythros = red, and opsis = sight) is a temporary distortion of colour vision. This phenomenon is a chromatopsia or impaired vision. It consists of seeing all objects with a uniform reddish tint. This vision symptom usually alarms the patient.
Monochromatism, dichromatism, and anomalous trichromatism are the three types of color blindness. These can be further broken up into tritanopia, deuteranopia, and protanopia to determine which colors and hues are not visible based on the cones present in the retina.
Tritanomaly is the rarest of all color blindness conditions, affecting well under 0.01% of both males and females. People who experience Tritanopia are lacking in blue cone cells. Blue appears identical to green and yellow is easily mixed up with violet or even dark grey.
Some color blind users are lacking the capability to detect the lower color wave frequencies associated with red. For these users, red color waves read as "no signal", or "black". These users confuse red and black, so this contrast should be avoided whenever possible.
The first rule of making a palette for colorblind – avoid combining red and green. So if you're aiming to create a color blind-friendly palette try to use only two basic hues: blue and red (orange and yellow will also fit). The other colors should be made out of these two hues.
People with protanopia color blindness lack the red detecting cone cells or pigments. As a result, they do not see red or orange colors as well. But they see all the other colors just fine.
#3: Which colors do you see then? All colors, many colors, less colors. Nobody suffering from color blindness can answer you this questions correctly. Some may see more, some less but none can tell you which colors, because a colorblind person doesn't know how you see the world.
Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.
A person with protan type color blindness tends to see greens, yellows, oranges, reds, and browns as being more similar shades of color than normal, especially in low light. A very common problem is that purple colors look more like blue.
