Screens vary
Calibration, brightness, Night Shift, True Tone and even room lighting change how colours look.
How mixing works
Recipes are predicted with spectral.js using Kubelka-Munk pigment theory. The closest match with the fewest clays wins.
Guides, not formulas
Recipes are a starting point. Clay brand, batch and how precisely you measure all affect the result. Always mix a test chip first.
Baking shifts colour
Oven temperature and baking time can shift colours. Follow the manufacturer's baking instructions.
