Color Psychology

Positive Moves (Green Spectrum)

  • Brilliant (#1baca6): Teal stands out as special/unique
  • Great (#5c8bb0): Blue-green suggests strong but not perfect
  • Best (#81b64c): Pure green = optimal choice
  • Excellent (#96bc4b): Lighter green = very good
  • Good (#96af8b): Muted green = acceptable

Negative Moves (Yellow-Red Spectrum)

  • Inaccuracy (#f0c15c): Yellow = warning, minor issue
  • Mistake (#e6912c): Orange = more serious problem
  • Blunder (#ca3431): Red = critical error

Implementation Details

Changes Made

    • Consistent with chess education materials
    • Professional appearance

Arrow Colors (New Feature)

Arrows now show for ALL moves (not just mistakes) and are color-coded:

Move Quality Arrow Color RGBA Value
Best/Excellent Green rgba(129, 182, 76, 0.8)
Great/Good Blue rgba(92, 139, 176, 0.8)
Inaccuracy/Mistake/Blunder Red rgba(202, 52, 49, 0.8)

Visual Effect

  • Green arrows: Shows engine's recommendation is aligned with player's choice
  • Blue arrows: Shows a good alternative move
  • Red arrows: Shows player missed a better move

This provides immediate visual feedback on move quality without needing to read the classification label.
