Color Mixing Rules

Mistura Subtrativa

Vermelho + azul = roxo. Amarelo + azul = verde. Vermelho + amarelo = laranja. Branco clareia. Preto escurece. Sempre misture mais do que precisa — reproduzir uma mistura manual é quase impossível.

No Brasil

As lojas de tintas (Suvinil, Coral) oferecem sistema de colorimetria: escolha a cor e a máquina mistura com precisão. R$5-15 a mais por lata. Muito mais preciso que misturar manualmente.

⚡ CalcWolf Insight

Professional painters never mix custom colors by feel — they use precise measurements and record the exact ratio. Keep a written record of your custom mix (e.g., "32 oz Color A + 12 oz Color B") so you can reproduce it if needed. Take a photo of the dried result next to the ratio for future reference.
