Color Discrimination Training for Children

The Challenge

Children with congenital color vision deficiency, especially mild-to-moderate anomalous red-green differences where some color signal remains, can have trouble distinguishing colors in school, games, maps, charts, art activities, and everyday sorting tasks. The child may see the object, but the color cue that classmates use instantly is unreliable.

Current approaches mostly focus on screening, diagnosis, classroom or environmental adaptations, and color-filtering glasses or lenses. This challenge is explicitly experimental: perceptual training has not yet been shown directly to improve congenital color vision deficiency in children, and a game cannot restore a missing cone channel. Early evidence for chromatic perceptual learning and neural adaptation in anomalous trichromats makes this a useful research question, not an established treatment claim.

What a Jam Prototype Could Be

• A hidden-object game that calibrates difficulty to a child's color-vision profile.
• Existing exercise concepts translated into play: repeated color matching, odd-one-out detection, shade ordering, figure-ground search, and adaptive discrimination between near colors.
• Levels that gradually reduce contrast between target and background, add distractors, or shift the same task into school-like contexts such as maps, lab materials, or toy sorting.
• A screening mode that estimates which color pairs are hard for the player, then builds a training ladder from easier to harder pairs.
• A progress view showing whether the child improves on specific discriminations without claiming to cure color blindness.
• A research mode that measures color-discrimination thresholds before and after training, then tests untrained colors or real-world tasks to look for transfer.

Design Questions

• Which color pairs should be tested first?
• How can the prototype avoid pretending to cure color blindness?
• Which untrained tasks could show whether any improvement transfers beyond the game?
• How can the game stay fun when the target is deliberately hard to see?
