How to Check If You’re Color Blind at Home (Simple Test Guide)

Color is essential in many daily activities such as driving, clothing selection, and interpreting data. However, what if your perception of colors is different from everyone else’s?

Most people are unaware of the conditions of their color perception. If you often find it difficult to distinguish tones of various colors, or if you often find yourself contradicting others' perspectives, you may consider yourself color blind?

Fortunately, if you want to gain a better understanding of your color perception, you don’t have to spend money on fancy tools or make hospital visits. Currently, it is possible to color blindness tests from the comfort of your home at no cost.

Everything else you may want to find out from PoXnT can be anything from the symptoms, the different variations of CVD, and what you can do to test your color perception at home to what you can do to test it using the internet.

🎯 What Is Color Blindness?

Color blindness, or color vision deficiency (CVD), is a condition where an individual has a hard time identifying specific colors.

Color blindness is results from dysfunctional retinal cells (cones) which are responsible for color perception. Cones respond to specific wavelengths of light and their primary colors are red, blue, and green.

When one or more types of cones are not functioning properly, your capacity to perceive colors accurately may be reduced or changed.

🔬 How Normal Color Vision Works

To understand color blindness, it's useful to know how color vision works:
A normal human eye has three types of cone cells:

• The human eye contains three types of cone cells:
  • Red-sensitive cones
  • Green-sensitive cones
  • Blue-sensitive cones
• These three types of cone cells work together to interpret different wavelengths of light to produce color experience, which the brain interprets to produce the colors we see.
• Missing or malfunctioning any of the above cone types results in color confusion.
• Possible Symptoms of Color Blindness

⚠️ Common Signs You Might Be Color Blind

Color blindness results more often than not in some subtle changes in perception, which leads to most people not discovering this condition until completing a color blindness test.
A few indicators are listed below:

🔴 Color Confusion

• Red and green color confusion
• Problems differentiating colors from one another, for example, blue and purple

🎨 Color Perception

• Problems in correctly determining the colors of an object or a picture

📊 Problems Color-coded Data

• Problems interpreting data from a graph, a chart, or a map

👕 Problems in Identifying Outfits

• Problems wearing clashing or mismatched clothes

🚦 Problems in Recognizing Traffic Signals

• Problems in quickly recognizing the color of a traffic signal

💡 If you exhibit one or more of the above, nothing is more convincing for taking a color blindness test than these indicators.

🧪 Testing for Color Blindness With House Hold Materials

You don't need to beat me with medical tools to get started, here's the most simple and efficient method to test color blindness:

1️⃣ Ishihara Plate Test (Gold Standard)

The Ishihara test is the most reliable and most commonly used method of testing for color blindness.

How It Works:

• You are shown a series of circles with colored dots
• Each image hides a number/pattern
• Someone with normal vision would easily pick out the number
• Someone with color blindness might see a different number, or none at all

Why It Works:

The test is trying to see how different people with different types of color blindness see contrast and how they see color.

👉 At PoXnT, you can take this test at any time, and get accurate results.

2️⃣ Color Matching Test

This is a simple observational method:

Try This:

• Pick a set of objects that have a similar color, and try to match them to the correct color

What to Look For:

• Frequent mismatches and confusion between similar tones

This test might not be scientific, but it can reveal patterns in your perception.

3️⃣ Online Color Blind Tests

With the massive growth of technology, testing for color blindness has become significantly easier.

Advantages:

• No installation needed
• Results in 2 minutes or less
• Available on desktops and mobiles

🚀 PoXnT offers a free, simple, and optimized color blind test online

4️⃣ Check Family History

Color blindness can be hereditary, especially red-green color blindness.

You should consider:

• Do any of your relatives have the same problem?
• Has there been a diagnosis in the family?

👉 There is a strong possibility.

👁️ Types of Color Blindness Explained

When interpreting your results, knowing the type of color blindness is beneficial.

🔴 Red-Green Color Blindness (Most Common)

This condition affects the ability to distinguish between different shades of red and green.

Subtypes:

• Protanopia – Less sensitivity to red
• Deuteranopia – Less sensitivity to green

📊 This condition affects millions of people across the globe, more so men.

🔵 Blue-Yellow Color Blindness

This condition is less common than Red-Green Color Blindness, however, it is still significant.

Symptoms include:

• Difficulty in distinguishing blue and green
• Confusion between yellow and light colors

⚫ Complete Color Blindness (Achromatopsia)

In this rare condition, the affected is completely color blind with the following characteristics:

• The world is seen in gray
• There is light sensitivity
• There is reduced clarity of sight

⚖️ Are Home Color Blind Tests Accurate?

This is a common question.

✅ What Home Tests Can Do:

• Provide early detection
• Identify some possible concerns
• Provide some simple and quick insights

❌ Limitations:

• They do not provide medical diagnosis
• The condition of the environment in which the test is taken, such as screen brightness or lighting can change the outcome
• They may not identify all the possible color blindness

👉 That’s why tools like PoXnT are designed to be as accurate as possible while remaining accessible.

💡 Tips for Testing at Home

For improved accuracy, try the following suggestions:

• Make sure the room lighting is good
• Set the brightness on your screen to normal
• Avoid using night shift or blue light blocking filters
• Answer the questions truthfully
• Take the test multiple times to improve accuracy
