- Ratios auto-normalize if they don't sum to 100%
- Always mix slightly more than needed — color matching is difficult

Frequently Asked Questions
How do I mix custom paint colors?
Start with the lightest color as your base. Add darker colors in small amounts — it takes much less dark to shift a light color than vice versa. Mix thoroughly between additions. Keep notes of ratios for reproducibility.
Can I mix different brands of paint?
Same type only. Latex with latex, acrylic with acrylic, oil with oil. Mixing different types can cause curdling, poor adhesion, or uneven drying. Within the same type, different brands generally mix fine.
How do I match an existing color?
Most paint stores offer color matching from a sample or photo. For DIY, mix in small test batches, apply to cardboard, and let it dry — paint dries darker. Keep precise ratio notes once you achieve the right color.
Is the Paint Mixing Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
