Humans can't reliably recall colors. This assessment measures how closely you can recreate target colors after a short delay.

We'll show five target colors, then you'll rebuild each one from memory.

Color memory direct answer

Color Memory Test

Color Memory Test measures short-term recall for color appearance. You see a target color, wait briefly, then recreate hue, saturation, and brightness from memory.

The score uses CIEDE2000 Delta E after converting target and submitted colors into Lab-style coordinates. Delta E is the measurement vocabulary; the 0-10 score is a product-calibrated display curve.

This is not a color-vision diagnosis or professional certification. Screen calibration, brightness, color profile, ambient light, and device differences can change results.

Evidence at a glance

5 rounds per standard run
3 HSB controls: hue, saturation, brightness
Delta E 00 CIEDE2000 color-difference basis
3 visible source references
Target source

Seed-generated HSB targets, so the same seed can reproduce the same run.

Measurement

CIEDE2000 Delta E plus hue, saturation, and brightness drift summaries.

Report use

Average Delta E, strongest drift direction, round consistency, and same-seed comparison.

Boundary

Not a clinical color-vision test, color-grading certificate, or permanent visual-memory claim.

Evidence

What authority supports this test?

The app converts target and submitted colors into RGB and CIE Lab coordinates, then measures color difference with the CIEDE2000 Delta E formula.

The cited CIE and W3C sources support color-difference and color-space concepts. They are not endorsements or certifications of Dialed Color.

Target fairness

How same-seed comparison stays fair

Bot Challenge is labeled as a system rival, not a hidden human.

Friend Challenge and Live Match use the same seed, difficulty, and round count, so both sides receive the same target colors and scoring model.

Limits

What can affect the result?

Screen calibration, brightness, color profile, ambient light, and the user's display all affect results.

Report meaning

What the color report should explain

A useful color report separates hue misses from saturation and brightness drift. One high-error round means something different from five medium-error rounds.

The report should also explain display limits, because the same target can look different across screens and lighting conditions.

Result analysis

How to read a color memory result

1 Start with total score

The 0-50 total is a quick summary of five color reconstructions. It is useful for comparison, but it does not explain the reason for the miss by itself.

2 Separate the drift

Hue drift means the color family moved. Saturation drift means vividness changed. Brightness drift means the remembered color became lighter or darker.

3 Check consistency

One bad round suggests a momentary miss; repeated medium misses suggest a stable memory pattern worth comparing with same-seed runs.

FAQ

Color memory FAQ

Is Delta E the score?

No. Delta E is the color-difference measurement. Dialed maps it to a 0-10 assessment score for readability.

Are the colors random?

They are seed-generated pseudo-random targets. Same seed, difficulty, and round count reproduce the same target set.

Why can my score change on another screen?

Different screens, brightness, color profiles, and ambient light can change perceived color.

Can this diagnose color blindness?

No. It is a memory and recreation task, not a clinical color-vision diagnosis.
