The 12 suits of the free, printable, 162-card Rainbow Deck might be useful for piecepack game designers who would like to expand the 12 suits made by combining a standard piecepack, playing cards piecepack, and seasonal piecepack.
piecepack suit | Mesomorph color | JCD color | Suggested Rainbow Deck color | Mnemonic |
Suns | red | red | red | same as basic piecepack |
Crowns | yellow or green | green | yellow | same as basic piecepack |
Arms (JCD: Anchors) | blue | blue | dark blue | same as basic piecepack |
Moons | black | black | black | same as basic piecepack |
Spring (Flowers) | light blue | purple | light blue | same as original Mesomorph |
Summer (Fish) | purple | light blue | dark purple | same as original Mesomorph |
Autumn (Leaves) | orange | orange | orange | same as Mesomorph and JCD |
Winter (Snowflakes) | white | white | gray | close to Mesomorph and JCD |
Hearts | red | red | pink | color of love; pink = light red; goes with light purple (other red suit) |
Spades | black | black | light green | blade of grass; both black suits are green |
Diamonds | red | red | light purple | goes with pink (other red suit) |
Clubs | black | black | dark green | clover; both black suits are green |
I had originally mapped Spring onto light purple and Diamonds onto light blue, but MartyHaleEvans made a good case for reversing these (see comments). Most of the original colors of the basic and seasonal piecepacks are now preserved. However, the playing card suits are now red(dish) and green instead of red and black.
Like the JcdPiecepack, the Rainbow Deck is divided into light and dark suits. Unfortunately, there doesn't seem to be a sensible, non-arbitrary way to map the light and dark suits of the Rainbow Deck onto the JcdPiecepack.
