Abstract: A method of establishing a paint color to be displayed by a procurement system based on information received from an external punchout site. A formula corresponding to a desired paint color selected by a customer that is not included in a color palate of predefined colors regularly available for purchase from a paint supplier is received. Based on the formula, a standardized color value within a color gamut of the electronic display device is generated for the desired paint color. The standardized color value is stored in a network-accessible database entry specific to the customer to be retrievable by the customer over a communication network for generating a preview of the desired paint color during a subsequent purchase of paint having the desired paint color by the customer over the communication network.
