Have you ever tried a color vision test? These tests are designed to check whether someone has a color vision deficiency - a condition that is typically inherited. When color vision is impaired, it becomes harder to distinguish between certain colors, and in some cases, a person may have one of the four main types of color blindness.

Interestingly, many people with color vision deficiency don’t realize they have it. They often only notice in everyday situations - for example, when stopping at traffic lights and feeling unsure about which color is being displayed. In most cases, individuals with color vision deficiency have difficulty telling apart shades of red and green or distinguishing between blue and yellow tones.

So, what exactly is true color blindness?

Many people use the terms color blindness and color vision deficiency interchangeably, but they are not exactly the same. True color blindness - where someone sees only in shades of black, white, and gray—is extremely rare. Most individuals who are “color blind” actually experience color vision deficiency (CVD), meaning they have difficulty distinguishing certain colors, most commonly red and green.

This article offers a simple, engaging way to reflect on how your eyes perceive color. It’s not a diagnostic test, but it can give you insight into whether your color perception might differ from typical vision. The idea is straightforward: if you can easily identify each of the following colored words, your color vision is likely functioning normally. If some are difficult to distinguish, it may point to a variation in how your eyes process color.

Let’s go through them one by one.

1. Can You See the Blue Word?

Blue is an interesting starting point. Even for individuals with color vision deficiencies, blue is often one of the easiest colors to perceive. That’s because the human eye detects blue using a different type of photoreceptor than those responsible for red and green.

For people with red-green deficiencies, blue can act as a kind of visual “anchor”—a stable reference point in a world where other colors may blend together. If blue appears clear and distinct, that’s completely expected, even for those with mild color vision issues.

2. Can You See the Green Word?

Green is more complex. It sits right in the middle of the spectrum most affected by common forms of color vision deficiency.

Some individuals can still recognize green quite well, especially when:

• The brightness is strong
• The contrast with surrounding colors is clear
• Context provides clues (for example, traffic lights or plants)

Because green is so common in nature and daily life, many people unconsciously learn to interpret it using context and experience, even if their perception isn’t perfectly accurate.

3. Can You See the Purple Word?

Purple is where things get more challenging.

Why? Because purple is not a “pure” color—it’s a blend of red and blue. If someone has difficulty perceiving red or blue, their interpretation of purple can shift significantly.

• With red-green deficiency: purple may look more blue
• With blue-yellow deficiency: purple may lose its red tone and appear duller

Even so, surrounding colors and brightness differences often help the brain “fill in the gaps,” allowing many people to still recognize it.

4. Can You See the Pink Word?

Pink can be surprisingly tricky.

Since pink is essentially a lighter version of red, individuals with difficulty perceiving red may see pink as:

• Faded
• Grayish
• Less vibrant than expected

However, pink is often used in very distinct contexts—fashion, branding, or design—which helps people identify it even if the color itself isn’t perceived accurately.

5. Can You See Another Blue Word?

Revisiting blue reinforces its importance.

Blue continues to stand out as a reliable color for most people, including those with color vision deficiencies. Its clarity comes from the fact that it is processed by a separate visual pathway in the eye.

This makes blue less likely to be confused with other hues, and it often remains one of the most stable colors in visual perception.

6. Can You See the Orange Word?

Orange sits between red and yellow, which makes it more complicated.

Depending on the type of color vision deficiency:

• It may appear more yellow
• Or shift closer to red
• Sometimes it loses its richness altogether

Despite this, orange is commonly associated with recognizable objects—like fruits or warning signs—which helps the brain interpret it correctly using contextual cues.

7. Can You See the Purple Word Again?

Purple appears again because it’s one of the most revealing colors when it comes to color perception.

Since it depends on both red and blue signals, any imbalance in those channels can change how purple looks. Some people may see it as deep blue, while others may perceive it as a muted or unclear shade.

This makes purple a useful “test color” for understanding how the brain blends visual information.

8. Can You See the Red Word?

Red is one of the most commonly affected colors in color vision deficiency.

For some individuals, red may appear:

• Darker than it should
• Brownish
• Or even slightly green

This can have real-world implications, especially in situations like reading traffic signals or identifying ripe food. However, most people adapt remarkably well, using brightness, position, and context to compensate.

So, What Does This Mean?

If you were able to recognize all eight colors quickly and clearly, your color vision is likely within the typical range. If some colors felt harder to distinguish, it doesn’t necessarily mean something is wrong - it may simply reflect a variation in how your eyes perceive color.

Color vision deficiency is more common than many people realize, and most individuals who have it live perfectly normal lives without major limitations.

Final Thoughts

This exercise isn’t about passing or failing - it’s about awareness.

Color perception is not just about the eyes; it’s also about how the brain interprets signals. Two people can look at the same image and experience it differently, and both perceptions are valid within their own context.

If you’re ever unsure about your color vision, a professional eye exam can provide clear answers. But for now, take this as a reminder of how fascinating—and complex—human vision really is.
