The phase scale
Five states, symmetric around neutral.
Every timeframe resolves to one of five phases with a numeric value and a colour: impulse up at +2 renders lime, corrective up at +1 teal, neutral or mixed at 0 gray, corrective down at −1 orange, and impulse down at −2 red. The symmetry matters for reading speed — the eye distinguishes lime and red instantly, and teal versus orange nearly as fast, so a stacked panel communicates directional bias before any counting happens. The impulse/corrective distinction is the structurally important one: lime and red mark trend legs, while teal and orange mark counter legs, and a panel full of impulse colours means directional wind at your back.
