Bigg Boss 19 Finalist Gaurav Khanna’s Color‑Blind Revelation – What It Means and How It Can Be Treated

When the popular Indian reality show Bigg Boss 19 finished its final week, a surprising confession turned headlines: Gaurav Khanna, the show’s runner‑up, announced that he is color blind. The revelation was more than a quirky piece of gossip—it opened a conversation about a condition that affects roughly 8 % of men worldwide and less than 1 % of women. In this article we’ll unpack the facts behind color blindness, examine Khanna’s experience, and explore the ways the condition can be diagnosed and managed.

1. Gaurav Khanna’s Public Disclosure

During a post‑show interview on the Bigg Boss launchpad, Gaurav—known for his outspoken personality—disclosed that he had struggled with color perception since childhood. He explained that he had to “learn to distinguish between shades that most people see differently.” The actor went on to say that the diagnosis was confirmed only a few weeks before the finale, when a routine eye‑care visit revealed a red‑green anomaly. Khanna’s honesty sparked empathy among fans, many of whom had never considered the everyday challenges of color blind people.

The episode also highlighted how color blindness can affect public perception. Khanna noted that on set, the vibrant wardrobes and set designs were often “overwhelming” for him, and he had to rely on lighting cues and textures to orient himself. He ended his statement with an invitation to people with similar conditions: “If you’re out there, we’re all in this together.”

2. What Is Color Blindness?

Color blindness, or color vision deficiency, is a condition in which the cones in the retina do not function properly. These cones—red, green, and blue—allow humans to perceive a spectrum of colors. When one or more cone types are absent or function abnormally, color discrimination becomes impaired.

The most common form is red‑green color blindness, which is inherited in an X‑linked recessive pattern. As a result, men are disproportionately affected because they carry only one X chromosome. Women, possessing two X chromosomes, are usually carriers and rarely show symptoms unless both X chromosomes carry the mutation. Blue‑yellow color blindness is rarer and is often linked to other systemic conditions, while total color blindness (achromatopsia) is extremely uncommon.

3. Symptoms and Everyday Impact

People with color blindness may not “see” colors as the rest of the world does. Typical symptoms include:

For Gaurav Khanna, the practical implications were clear: bright, saturated costumes could blend, and subtle color gradients in the house could mislead him about his surroundings. The frustration extends beyond entertainment—it can affect job performance, safety (e.g., traffic signal recognition), and social interactions.

4. How Is Color Blindness Diagnosed?

Modern ophthalmology offers a range of diagnostic tools:

1. Sobel Test – A simple paper‑based test that requires the patient to read a number or shape formed from colored circles.
2. Ishihara Plates – The gold‑standard test in many countries; it uses plates with colored dots to create a number or shape visible only to those with normal vision.
3. Anomaloscope – A sophisticated instrument that measures the patient’s cone response to various wavelengths.
4. Genetic Screening – Identifies mutations in genes such as OPN1LW and OPN1MW, especially useful for counseling and potential future gene therapy.

In Khanna’s case, the eye doctor used a combination of Ishihara plates and an Anomaloscope to confirm a protan‑type (red‑green) deficiency.

5. Treatment and Management Options

While color blindness cannot be “cured” in the traditional sense, several interventions can help people adapt or partially restore normal color perception:

5.1. Color‑Correcting Lenses

Specialized glasses and contact lenses—often marketed as Prizm or ColorCorrect—contain optical filters that enhance color contrast. They do not “fix” the cone defect but improve differentiation of certain hues.

5.2. Digital Aids

Mobile apps and computer software can transform images in real time, providing color cues or labeling colors for the user. Some games even adapt to the user’s vision profile, offering a more inclusive experience.

5.3. Gene Therapy

Clinical trials using viral vectors to deliver healthy cone‑specific genes have shown promise in early‑stage studies. While still experimental, gene therapy could, in theory, restore full color perception in the future.

5.4. Adaptive Strategies

Education and self‑help strategies—such as learning to rely on texture, brightness, and placement—are often the most immediate ways people cope. Khanna himself mentioned using “non‑color cues” on the Bigg Boss set to stay oriented.

6. Cultural and Social Dimensions

Color blindness carries cultural implications that vary worldwide. In India, for instance, festivals are rich in color symbolism, and color perception is deeply woven into social rituals. People with color blindness often face misunderstandings—e.g., misinterpretation of garb colors or misreading of warning signs.

Khanna’s openness has broadened awareness among a large fan base. Social media threads show fans applauding his transparency and sharing their own experiences. The narrative also highlights the need for media representation of color‑blind individuals, especially in roles where visual accuracy matters.

7. Notable Color‑Blind Personalities

History and pop culture offer several inspiring examples:

• Thomas Edison – The inventor’s red‑green deficiency reportedly spurred his fascination with light bulbs.
• David Bowie – His stage costumes were carefully designed to avoid colors that were problematic for him.
• Stephen Hawking – Though his condition was more complex, he is often cited as a figure who proved that visual perception isn’t the sole determinant of success.

These stories illustrate that color blindness need not impede ambition or creativity.

8. Take‑away Messages

1. It’s More Common Than You Think – Men in particular are often color blind, though the condition can be overlooked until a formal test confirms it.
2. Diagnosis Is Simple – Tools like Ishihara plates and genetic tests are accessible, and early detection can help users adapt.
3. Management Is Multi‑Faceted – From optical aids to digital solutions, there are numerous ways to mitigate visual challenges.
4. Awareness is Key – Gaurav Khanna’s candid confession serves as a reminder that visibility can foster understanding and inclusivity.

In closing, color blindness remains a visible reminder that human perception varies. By acknowledging and supporting those who experience the world in different hues, society can become more empathetic, creative, and inclusive. Gaurav Khanna’s revelation has opened a dialogue that goes far beyond a reality‑show confession—it’s a conversation about adaptation, resilience, and the rich tapestry of human vision.
