Abstract: Disclosed are a color-designating server which can display a screen for designating color at a user terminal, which can be connected to a network, a color-designating method, and a recording medium. A matchable color database stores data required for determining matchable colors in a color-designating server which displays a screen for designating color at a user terminal. A conditions-designating processor transmits a conditions-designating screen for designating conditions data, required for determining the matchable colors, to the user terminal. A color data transmission processor determines colors which can be matched under the conditions specified by the conditions data, designated in the conditions-designating screen, by consulting the matchable color database, and transmits the result to the user terminal.
