Every Dialed GG color round is scored 0–10. Five rounds, maximum 50. But what goes on behind those numbers? This guide breaks down the three layers of accuracy that make every Dialed GG score fair, meaningful, and rooted in color science.
Nearly indistinguishable from the target. Elite-level recall.
You nailed the color family and most of the nuance.
Right neighborhood, but brightness or saturation drifted.
Wrong region of the spectrum — a significant perceptual gap.
The guess and target look like entirely different colors.
Your Dialed GG color score is not a simple slider comparison. Raw HSB values would produce wildly unfair results — the same numerical shift on a hue slider can look invisible on one color and dramatic on another.
Instead, both colors are converted into CIELAB — a perceptually uniform color space created by the International Commission on Illumination (CIE), where equal numerical distances correspond to equal perceived differences. The distance between your guess and the target is then measured using CIEDE2000 (ΔE₀₀), the most accurate Delta E formula in color science.
This is the same standard used in print production, display calibration, and industrial quality control. Analyses across 50,000 random color pairs confirm that CIEDE2000 eliminates the unfair 3:1 hue-region biases found in older CIE76 formulations.
Both colors are converted from HSB → RGB → CIELAB, then the perceptual distance is calculated with corrections for lightness, chroma, and hue sensitivity. A ΔE₀₀ of 0 means identical; values above 50 are completely different colors.
The raw ΔE₀₀ distance is mapped to a 0–10 game score through a sigmoid curve: 10 / (1 + (ΔE / 25.25)^1.55). This curve is generous for close matches, steep in the competitive mid-range, and compresses bad guesses toward 1–2. Precision matters most above 7/10.
Two game-design adjustments reward true color memory:
