A strong color mixing game strategy is to compare the target’s hex and Lab values, adjust one slider at a time, and aim for Delta E 1976 of 3.0 or lower before checking.
The Color Mixing Game gives you five fixed targets across RGB and idealized CMY modes, so a precise, repeatable process is more useful than guessing from the swatch alone.
Read the numeric target first
Begin with the labels rather than the apparent brightness or saturation of a color patch. Each round provides the information needed to establish the active model and compare the target with your current mix.
- Active model: Check whether the round is labeled RGB or Idealized CMY.
- Target hex: This is the encoded sRGB value you are trying to reproduce.
- Target Lab: These L, a, and b coordinates provide the color coordinates used for scoring.
- Current mix: Read its hex, RGB channel numbers, and Lab coordinates beside the target.
More than two color patches appear in every round, so identify the labeled target and current mix instead of assuming that the brightest or most saturated patch is the one to copy. The text and numeric cues keep the state understandable even when two colors look similar, a display is not calibrated, or players perceive the difference differently.
Choose the model shown on screen
RGB and CMY are deliberately different systems. The controls may look similar, but the direction of a useful adjustment reverses between the two models.
| Round model | Control behavior | Useful first-pass comparison |
|---|---|---|
| RGB | Red, green, and blue sliders range from 0 to 255. Raising a control adds more of that encoded sRGB component. | Compare the current red, green, and blue numbers directly with the corresponding components of the target hex. |
| Idealized CMY | Cyan, magenta, and yellow range from 0% to 100%. Cyan removes red, magenta removes green, and yellow removes blue. | Derive the resulting red, green, and blue channels from the CMY controls, then compare them with the target hex. |
The disclosed CMY complement rule can be written as R = round(255 × (1 − C/100)), G = round(255 × (1 − M/100)), and B = round(255 × (1 − Y/100)), where C, M, and Y are the slider percentages. Each resulting display channel is rounded to an integer.
That means too much red calls for more cyan, while too little red calls for less cyan. The same relationship applies to magenta and green, then yellow and blue.
Play a target with a controlled adjustment loop
- Read the entire round before touching a control. Confirm the active model, target hex, target Lab coordinates, and the current mix’s hex, RGB values, and Lab values.
- Choose a direction from the numbers. In RGB, compare each current channel with the target hex: raise a channel that is too low and lower one that is too high. In CMY, convert the controls into display channels and reverse the corresponding adjustment direction.
- Make one small adjustment. For precise keyboard control, focus a slider with Tab and use the arrow keys for one-unit changes. Mouse and touch controls provide the same three adjustments, with touch interaction heights of at least 44 pixels.
- Read the updated mix. Look at the new hex, RGB channels, and Lab coordinates. Decide which single numeric difference still needs attention instead of changing all three controls at once.
- Translate that difference into another one-control move. If the current red channel remains below the target red channel, raise red in RGB. If it remains above, lower red. In CMY, use more cyan for excess red and less cyan for deficient red.
- Use Lab values as a second opinion. Similar RGB numbers do not serve as a Delta E calculation. Compare the current L, a, and b coordinates with the target’s coordinates to confirm that the mix is moving into the same neighborhood.
- Press Check mix when the numeric cues appear close. The check evaluates the current controls through the actual color-conversion process rather than through a shortcut based on summed RGB gaps.
- Interpret the result before proceeding. A Delta E 1976 value of 3.0 or lower is accepted, awards 200 points, and opens the next fixed target. A first distinct wrong mix records its Delta E and leaves one chance for a considered revision.
- Repeat the same discipline for all five rounds. Do not weaken the process after an early success: identify the model, make one directional adjustment, compare the numbers, and then check.
Use Lab and Delta E as the final arbiter
Delta E 1976 is the Euclidean distance between two CIELAB triplets: ΔE76 = √((L1 − L2)² + (a1 − a2)² + (b1 − b2)²). A smaller value means the two Lab coordinates are closer; RGB channel distance is never labeled or used as Delta E.
The game performs a full conversion chain before calculating that distance. It normalizes and decodes the encoded sRGB channels with the piecewise sRGB transfer function, converts linear light through the sRGB-to-XYZ matrix for D65, normalizes XYZ against the D65 white point, transforms the result into CIELAB, and then applies the Euclidean formula.
For strategy, this creates a useful division of labor: use hex and RGB to decide which channel should move, then use Lab and Delta E to judge whether the resulting mix is close enough. The conversion chain follows the procedure published in W3C CSS Color Module Level 4’s color-conversion code, with the sRGB definition cross-checked against the International Color Consortium’s sRGB registry.
Keep CMY and paint expectations separate
Idealized CMY is a teaching model for complementary display channels, not a simulation of pigment chemistry. It predicts how the game’s controls alter red, green, and blue under its disclosed simplification.
Real paint, printing ink, paper, lighting, binders, and pigments can behave differently because their spectral properties are not represented. Treat a CMY result as a digital mixing exercise rather than a recipe for predicting what will appear on a physical surface.
Treat each check as a deliberate decision
Check mix turns the current settings into an attempt, so use the button after the numeric comparison rather than as a random scanner. The miss structure makes that distinction important:
- The first distinct wrong slider signature records its Delta E and leaves one chance.
- Checking that exact same wrong signature again is deduplicated and does not consume the second chance.
- A second different wrong signature locks the round, disables all three sliders and the Check button, and leaves Restart as the only recovery path.
- Restart restores the same deterministic first target, zeroed sliders, zero score, and empty signature set.
Repeating an identical wrong signature offers no new color information, even though it does not consume the second chance. After the first unique miss, make one reasoned revision based on the updated comparison instead of trying an unrelated arrangement. If a second distinct miss locks the round, restarting begins a clean run rather than attempting to alter the disabled state.
Finish with a repeatable five-round routine
The fixed sequence combines RGB and idealized CMY tasks across Signal Orange, Ideal Green, Electric Cyan, Ideal Violet, and Screen Magenta. Each accepted match immediately awards 200 points and opens the next target, so five completed rounds produce an exact score of 1,000 points.
Use the same four-question check before every submission: Did I identify the active model? Does the adjustment direction follow the numeric comparison? Did I change only one control? Are the updated hex and Lab values close to the target? Because the challenges are fixed and Restart returns to the same first target, this routine also provides repeatable practice instead of presenting a newly randomized puzzle.
