When formulating color, everything, from a supplier using a new base, to water from a different location, will influence the end color. The paint and coating color formulation process requires standardizing conditions and procedures to match color standard efficiently. Color formulation involves defining requirements and methods while also identifying variables within the environment or production process that could influence the color formulation results. In addition, color measurement instruments such as spectrophotometers and sophisticated color formulation software, such as Colibri®, are essential for quantitative analysis to help achieve the right color with minimal time and waste.
