Chapter 02 Color rules
Deck field notes 03 / 12
The system

Make every signal count

Shout the rule. Keep it readable.

One bold oval and one fat glyph stay legible from across the table.

Primary signal

Turn the table. Make change visible.

A diagonal gesture gives every transition a direction you can feel.

Accent move

Stack the proof. Let detail follow.

Layered cards turn a simple action into a compact, unmistakable cue.

Info layer

Give four choices. Keep one voice.

Red, yellow, green, and blue do the talking; black makes them land.
