Color Blind Test

Welcome to our Color Blind Test, designed to help you check whether you have any color vision deficiencies.

What is Color Blind Test?

A color blind test is a screening test that helps determine if an individual has difficulty distinguishing colors. These tests typically involve using specially designed images or patterns of colored dots or shapes. The individual is asked to identify any numbers or patterns within the image.

The test results can help identify the type and issues of color vision deficiency the individual may have, which can help determine any necessary accommodations or treatments. There are various types of color blindness tests available, ranging from simple screening tests to more robust and necessary tests, which are administered by a qualified eye care professional.

How Does Color Blind Test Work?

The color blind test consists of circles with numerous dots and a Hidden number in them. The numbers are of different colors than their surrounding dots, but a color blind person will perceive all the dots as the same. However, a person with normal vision will easily be able to distinguish between the different colors and identify the hidden number.

Testing for color blindness is a crucial step in managing this common condition. With several types of tests available, individuals can receive an accurate diagnosis and begin receiving appropriate treatment and accommodations to ensure that they can lead fulfilling lives.

How to Get Accurate Results?

Remove Eyewear

For the most accurate results, please ensure you're not wearing any eyewear like glasses or contacts while taking the test. Using such items might affect the test's effectiveness and reduce result accuracy.

Turn Brightness too high

As you're likely aware, the level of light that reaches your eyes significantly impacts how well you can notice distinctions. To ensure you can identify any details on your screen, we recommend setting your brightness to the highest level.

Disable the Blue light filter

If you've activated a blue light filter on your device, please disable it before taking the test. The filter changes the screen's colors, potentially affecting result accuracy by making it difficult to identify the correct colors.

What makes someone color blind?

Color blindness, which mostly originates from birth but can also develop later in life, is primarily attributed to issues with the cones present in the retina. These problems often arise due to genetic anomalies inherited from parents, resulting in cones that are either improperly formed or completely absent because of abnormal genes. Among the various types of color blindness, one of the most common forms is associated with gene irregularities located on the X chromosome. Apart from genetic factors, certain health conditions such as Glaucoma, diabetic retinopathy, and Alzheimer's, as well as the side effects of specific medications, can contribute to the occurrence of color blindness.

Note: In the case of color blindness, men inherit the gene responsible from their mothers. Conversely, women develop this type of color blindness only when the gene is passed down from both their mother and father. This difference in inheritance is why color blindness is more prevalent among men.

Types of Color Blindness

Red-Green Type

Individuals with red-green color blindness may have difficulty checking between colors that contain shades of red or green, such as brown, purple, or pink. They may also have difficulty distinguishing between traffic lights, as the red and green lights may appear similar in color. Different types of Red-green color blindness are as follows.

Protanomaly: - because of the unusual incidence of red cone pigments. In this kind, pink, orange, and yellow seem inexperienced, and the colours aren't vivid. This condition is benign and usually does now not affect daily existence.

Protanopia: In this kind, the red cone pigments stop running, and the red will appears black. Some variants of orange, yellow and inexperienced all seem yellow. Some opticians use a reverse color blind check to diagnose color vision deficiency. In this check, the sufferers are requested to perceive the coloured object inside the pallet within the dynamic coloured heritage.

Deuteranomaly: This is the most not unusual kind of found in people. It has an unusual green cone pigment. Yellow and inexperienced appear purple, and red and blue are hard to perceive. This condition is benign and commonly does now not affect everyday life.

Deuteranopia: In this, inexperienced cone pigments stop operating. They see red shades as brownish-yellow and green as dark yellow.


Blue-yellow type is rarer than red-inexperienced. In this, the blue cone pigment (triton) is either absent or has a restricted feature. Different types of blue-yellow color blindness are as follows.

Tritanomaly: - Blue cone pigments have fewer characteristics. The blue shade appears green, and it can't be easy to distinguish from red to yellow and red.

Tritanopia:People with Tritanopia lack blue cone cells. Blue seems green in this, and the yellow shade seems red or light brown.

Full (Monochromacy) Type

People with a complete type monochromacy no longer see any colours, and their clarity of imagination and prescience can also be affected.

There are two kinds of monochromacy.
Cone monochromacy: - Two or three cone cell pigments do now not work. People with cone monochromacy have problems distinguishing colours because the brain wishes indicators from distinct varieties of cones to look. This contrast is only sometimes possible when the handiest sort of cone works.

Rod Monochromacy:- It is a gift from delivery. It no longer includes any of the to-be-had pigments of cone cells. People with rod monochromacy see the arena in black, white, and grey. People with rod monochromacy are photophobic and very uncomfortable in intelligent environments.

How to Test for Color Blindness?

Color blindness is nothing but a common condition which affects many individuals around the world. While it is typically inherited, it can also be caused by certain medical conditions or as a side effect of certain medications. Fortunately, there are various ways to test for color blindness, and early detection can help individuals manage their condition and make necessary accommodations.

One of the most common tests for color blindness is the Ishihara color plates test. This test involves a series of plates with colored dots arranged in a pattern, and the individual is asked to identify any numbers or shapes within the design. Individuals with normal color vision can see conditions or numbers, while those with color blindness may have difficulty seeing them.

Testing for color blindness is a crucial step in managing this common condition. With several types of tests available, individuals can receive an accurate diagnosis and begin receiving appropriate treatment and accommodations to ensure that they can lead fulfilling lives.


A reverse color blind test is a version of the Ishihara color test that is typically easily solved by someone who is color blind. Someone with normal vision would have difficulty seeing the number in the center of the image. If you fail a reverse color blind test, you most likely have normal, full-color vision.

Color blindness is primarily a genetic condition, so it cannot be entirely prevented. However, maintaining regular eye exams, understanding your family history, protecting your eyes from UV light, following a healthy lifestyle, using color-coded aids when necessary, and educating yourself about the condition can help promote eye health and minimize the challenges associated with color blindness.

Color blindness, particularly red-green color blindness, affects the ability to accurately perceive shades of red and green. Other types can impact blue and yellow perception. The specific colors affected vary based on the type and severity of color blindness in each individual.

Color-blind individuals have difficulty distinguishing specific colors, most commonly red and green, and sometimes blue and yellow, but the exact colors they can see depend on the type and severity of their condition. It's not a matter of seeing in black and white, but rather struggling with accurate color perception.

You can check for color blindness through our color blind test. The Ishihara test is a common example, using images with colored dots and numbers that people with normal color vision can see, but might be challenging for those with color blindness. However, for a definitive diagnosis, it's recommended to consult an eye care professional who can conduct comprehensive tests.

Yes, colorblind individuals can generally drive. Traffic signals and signs use shapes and positions, not just colors, to convey information. However, colorblind drivers should be aware of their limitations and take extra care in interpreting color-coded information. If concerned, consult with eye care professionals and driving authorities for guidance.
