Ready to Test Your Eyes?

Find the tile that's a slightly different color.
The grid gets bigger as you level up!

How to Play:
  • • Spot the different colored tile
  • • Click it to score points
  • • Wrong click = -3 seconds penalty
  • • Grid expands each level

This game tests your color perception and monitor's color accuracy. Better monitors make the game easier!

How to Play

1. Game Setup

  • Choose difficulty level (Easy/Medium/Hard)
  • Ensure good lighting (not too dark, avoid glare)
  • Sit at normal viewing distance
  • Take breaks every 10-15 minutes to avoid eye fatigue

2. Playing the Game

  • Match the target color by adjusting RGB sliders or HSL values
  • Get as close as possible to the target shade
  • Submit your answer to see accuracy score
  • Learn from feedback and try again

3. Score Interpretation

  • 95-100%: Excellent - Professional level
  • 85-94%: Very Good - Advanced amateur
  • 70-84%: Good - Competent color sense
  • Below 70%: Needs practice or calibration check

4. Improvement Tips

Practice regularly, start with easier levels, pay attention to hue/saturation/brightness separately, use proper lighting, ensure monitor is calibrated, and take breaks to prevent eye fatigue. Consistent practice yields measurable improvement within weeks.

The Ultimate Guide to Color Accuracy Testing

The Science of Color Perception

Human color vision relies on specialized cells in the retina called cones. Most people are trichromats, possessing three types of cones sensitive to Red (L), Green (M), and Blue (S) wavelengths.

1. Color Discrimination (Delta E): This game tests your ability to perceive minute differences in hue and saturation, often measured in "Delta E" (dE). A dE of under 2.0 is considered the limit of human perception for untrained eyes, while professionals can distinguish differences as low as dE 1.0.

2. Tetrachromacy Potential: A small percentage of the population (mostly women) may have a fourth type of cone cell, allowing them to see 100 times more colors than the average person. High scores in this game (Level 50+) can sometimes indicate superior color discrimination abilities.

Monitor Health Check

Your hardware matters as much as your eyes.

  • Panel Type: IPS and OLED panels generally make this game easier than TN panels due to better color reproduction.
  • Calibration: An uncalibrated monitor may crush blacks or blow out highlights, making subtle differences impossible to see.
  • Bit Depth: 10-bit displays offer smoother gradients than 8-bit ones, potentially aiding in color differentiation.

Brain Training

Neuroplasticity applies to vision too.

  • Perceptual Learning: Regular practice can actually "tune" your visual cortex to be more sensitive to specific color frequencies.
  • Attention Detail: This game trains sustained attention and visual search speed, useful for editors and gamers.
  • Eye Fatigue: Use this tool to identify when your eyes are tired; scores often drop significantly after long screen sessions.

Frequently Asked Questions

What is a "Pro" score in this game?

Level 1-20: Average (Untrained Eye)
Level 21-40: Good (Designer/Artist)
Level 41-60: Excellent (Colorist/Retoucher)
Level 60+: Exceptional (Potential Tetrachromat)

Does this test for color blindness?

Not medically. While difficulty distinguishing colors is a symptom, a proper medical diagnosis requires an Ishihara Test or an anomaloscope. However, if you consistently fail on specific colors (e.g., always losing on green levels), it's worth consulting an optometrist.

Why do I score lower at night?

Two reasons: Eye Fatigue and "Night Shift" modes. If you have a blue light filter (Night Shift/f.lux) enabled on your device, it drastically alters color rendering, making it nearly impossible to distinguish certain blue/purple shades accurately. Turn it off for the best score!
