Players take turns to describe a strong memory. never referring to any colors. At some point in their description they are challenged to say what color something in the memory was. Based on coin flips they either act confused, stating that they do not know, or state the color, before passing ceding control of the narrative to another player.
After each player has described a memory, another coin toss determines that either all those players who could not remember the color now remember (and must describe the return of clarity in their memory), or all those that remembered a color now forget it (and must describe the fading of their memory).
The game concludes with a period of quiet contemplation.
