// Seat 2's color, moved off seat 1's when the two resolve to the same color. Each seat's color
// comes from its own source (a selected profile's saved color, or a remembered guest/CPU color, see
// createSeatColorsSlice), and picking a profile has no swap step the way a manual recolor does, so
// a profile saved as the other seat's color would otherwise give both seats the same color. On a
// clash, seat 2 takes seat 1's default color, or seat 2's default when seat 1 is already on its own
// default. Colors compare case-insensitively. The result is for display, not for persisting: call
// it wherever the two seats' colors are resolved, so a guest's or the CPU's remembered color is
// left alone.
