Using the worksheet
- Worksheet opens the questions. New questions follow each mix; misses add a reflection prompt.
- Recorded automatically: each completed mix: section, recipe, predicted swatch letter/color, actual color, delta E, match status and stars. Revealing an answer is not a passed mix.
- My work offers Copy my work and Turn in a PDF. Nothing is submitted automatically. Review written reasoning separately from game success; blank responses remain visible.
- Worksheet answers and completed tries persist on this browser only. Game progress may reset on reload. Predictions are captured at launch and retained with each completed try. Do not enter identifying details.
- On shared devices, use Clear my work and tap again to confirm. The game's Start over does not clear worksheet answers. If browser storage is blocked, export before leaving.
Numbers like "#4" match the printed worksheet. Questions marked "After a miss" appear in the game only after a missed mix; on paper they are combined into one question near the end.
1A: Marigolds
- Exact smallest recipe: 1 red + 1 yellow. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#1. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 1 red + 1 yellow; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.
After a miss: Choose a missed try. What happened, and which rule would guide your next change? VA:Cr1.2.HSI
Use the recorded settings and result, identify the relevant rule, and propose a specific revision. Do not award credit for only copying a correct input.
1B: Hills and leaves
- Exact smallest recipe: 1 yellow + 1 blue. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#2. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 1 yellow + 1 blue; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.

1C: Irises
- Exact smallest recipe: 1 red + 1 blue. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#3. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 1 red + 1 blue; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.
#4. Why can 1 red + 1 yellow and 2 red + 2 yellow make the same orange, but earn different stars? VA:Cr1.2.HSI
Both have red:yellow = 1:1. This model depends on ratios, while the fewest-drops bonus rewards the smaller batch.

2A: Sky
- Exact smallest recipe: 1 blue + 3 white. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#5. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 1 blue + 3 white; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.

2B: Deep gold
- Exact smallest recipe: 4 yellow + 1 red + 1 blue. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#6. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 4 yellow + 1 red + 1 blue; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.
#7. Compare black with violet as a darkener for yellow in this model. Which result supports your choice? VA:Cr1.2.HSI
The model shifts blackened yellow toward olive. Violet (equal red and blue) is the complement used for the deep-gold target. Cite the hue or delta E from a tested mix. Real pigment behavior varies; this is a digital approximation.

3A: Brick
- Exact smallest recipe: 2 red + 1 yellow + 1 blue. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#8. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 2 red + 1 yellow + 1 blue; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.

3B: Warm gray stone
- Exact smallest recipe: 1 red + 1 yellow + 1 blue + 3 white. Match tolerance remains delta E < 8; near matches are valid. A correct swatch prediction is distinct from matching the restoration target.
#9. Record your recipe, predicted swatch letter, and measured color difference (delta E). Did your prediction match the result? VA:Cr1.2.HSI
One exact target recipe is 1 red + 1 yellow + 1 blue + 3 white; scaled copies have the same ratio and delta E 0. Record the actual selected swatch and measured result, even for a miss. A recipe passes when delta E is below 8; this does not prove its ratio is exact.
#10. Why do equal red, yellow, and blue plus white produce warm gray in this model? VA:Cr1.2.HSI
Equal primaries mix to brown in this model; an equal total of white lightens that brown. Three white drops balance the three colored drops. Black plus white is a different, cooler modeled mix.
After a miss: Choose a missed try. What happened, and which rule would guide your next change? VA:Cr1.2.HSI

When a mix missed (#11)
Any of the After a miss answers above. Look for the rule named correctly and the specific thing that went wrong.
Wrap-up
#12. Use a claim, evidence from two mixes, and reasoning to explain how a planned ratio helps restore a color. VA:Cr1.2.HSI
Claim: planned ratios control the modeled color. Evidence: two named recipes and observed results. Reasoning: connect ratio, tint, complement, or amount to those observations; acknowledge that the digital model approximates real paint.
