Where can you find the formula for mixing color in a mixing system?

The formula for mixing color in a mixing system is typically found in a computerized system or microfiche catalog. These systems provide precise formulations and allow for accurate color matching, which is crucial in automotive painting and refinishing. By using a computerized setup, professionals can input specific parameters and retrieve the exact mix ratios needed for the desired color, ensuring consistency and high-quality results.

While color swatch books do provide visual representations of various colors, they do not typically include detailed mixing formulas. A manual ledger might contain historical data of past mixes, but it lacks the precision and efficiency of a computerized system. Additionally, while instructions on the back of paint cans may provide mixing ratios for specific products, they don't generally contain comprehensive formulas for a wide range of colors suitable for a mixing system. Thus, the best resource for detailed mixing formulas is indeed a computerized system or microfiche catalog.
