A method and apparatus for producing a new color chart is provided. In this method, first, a standard color chart is output using an image output unit. Then, a colorimetric value of the standard color chart output by the image output unit is detected. Then, a new color chart is produced by reconstructing the standard color chart using the colorimetric value. Accordingly, the new color chart enables a device-independent color space to have a uniform color distribution. Thus, an interpolation weight obtained from the device-independent color space is stable, and an error in a color image output by a printer or the like is minimized.
