Underlying Game Design:

The 4 colors that make up the Frenopolis board are called "elements":
Fire, Air, Water, and Earth

All the board zones and card types are assigned 1 of these 4 elements.

Each card color (Red, Orange, Yellow, Blue, Purple, Violet) are defined as 2-combinations of the elements which comprise the board and the card types.

Defining all effects in terms of these elemental relationships allows a strict correspondence between the game board and color pie. The effect scope of each color is strictly defined and predictable.

You don't need to know this to play – you can just follow the written card text, but knowledge of the underlying design allows for more advantageous play.

For example:
A Purple (Psi) and Blue (Technology) deck will have a strictly predefined interaction scope:

Purple [Psi] (Air/Water) have effects which involve:
Memes (Air), Stories (Air), and Energies (Water)

in/to/from the:
Void (Air), Soul (Water), and Matrix (field)

Blue [Technology] (Air/Earth) have effects which involve:
Memes (Air), Stories (Air), and Structures (Earth)

in/to/from the:
Void (Air), Archive (Earth), and Matrix (field)

Purple (Air/Water) and Blue (Air/Earth) have an elemental conjunction (overlap) in the Air element. This means that a Purple/Blue deck will have effects which involve:

Memes (Air), Stories (Air), Energies (Water) and Structures (Earth)

in/to/from the:
Void (Air), Soul (Water), Archive (Earth), and Matrix (field)

Blue [Technology] (Air/Earth) have effects which involve:
Memes (Air), Stories (Air), and Structures (Earth)

in/to/from the:
Void (Air), Archive (Earth), and Matrix (field)

Purple (Air/Water) and Blue (Air/Earth) have an elemental conjunction (overlap) in the Air element. This means that a Purple/Blue deck will have effects which involve:

Memes (Air), Stories (Air), Energies (Water) and Structures (Earth)

in/to/from the:
Void (Air), Soul (Water), Archive (Earth), and Matrix (field)
