HOW SCORING WORKS
Every round, your color choice is measured and scored. Here's exactly how it works.
THE SCORING FORMULA
Points = (1 − ΔE ÷ 50) × 10,000 × Confidence
ΔE is the color difference in CIELAB color space. Lower ΔE = closer match = more points.
COLOR DIFFERENCE (ΔE)
After you pick a color, we calculate the Delta E (ΔE) — the perceptual color difference between the target and your pick. This uses the CIELAB color space, which models how the human eye sees color.
RAW SCORE
The raw score is max(0, 10000 × (1 − ΔE/50)). A perfect match (ΔE=0) gives 10,000 points. ΔE≥50 gives 0 points. Most good matches fall in the 5,000–9,000 range.
CONFIDENCE BONUS
Before locking in, you can choose Safe (×1), Risky (×1.5), or Gamble (×2). Higher confidence = bigger reward if you're close, but no penalty if you're wrong.
WHAT IS ΔE?
Delta E measures how different two colors look to the human eye. It's the industry standard used by designers, printers, and color scientists worldwide.
ΔE < 3
Imperceptible
Barely even experts can tell
~9,400+ pts
ΔE 3–8
Noticeable
Trained eyes catch it
~8,400+ pts
ΔE 8–15
Obvious
Most people see the difference
~7,000+ pts
ΔE > 15
Very Different
Clearly different colors
~<7,000 pts
RANK TIERS
Your rank is based on your average ΔE across all rounds. Lower average = higher rank.

Avg ΔE ≤ 20
Silver
Avg ΔE ≤ 25
Bronze
Avg ΔE > 25
TIPS TO IMPROVE
Memorize the hue first
Focus on the dominant color family (red, blue, green) before details.
Pay attention to brightness
Light vs dark makes a huge difference in ΔE. Don't pick too bright or too dark.
Use the Safe confidence
Start with Safe (×1) until you're consistently scoring above 70% accuracy.
