Definitions

  • An effective program of the type eliminates the need for further color adjustment by the refinisher. Although the system of this type eliminates the need for further color adjustment by the refinisher, the costs associated with the spectrophotometer or a colorimeter make it expensive to implement. Accordingly it is believed desirable to provide a less expensive computer-implemented tool that can be used for color matching by a refinisher to match a target color.
  • the multidimensional color space contains three dimensions.
  • the present invention may be utilized for color matching metallic or pearlescent hues, in which event a vector space of nine or fifteen dimensions is utilized.
  • Figures 1A through 1C are a series of stylized vector representations in a three-dimensional color space illustrating the V ⁇ laflonsf1ip ' "drri ' (5 ' n ⁇ a 1 " vector representing a predetermined target paint color, a vector representing an initial candidate paint color, and adjustments of the candidate paint color toward the target color using adjustment vectors based upon the tint colors constituting the initial candidate paint color; and
  • Figure 2 is stylized diagram of a computing system for executing a program implementing the method of the present invention, the stylized diagram including a representation of a screen display generated by a computer when implementing the method and program of the present invention.
  • Both white and black tints should normally be made available to ensure the ability to attain the correct lightness for an appropriate color match.
  • white and black tints also have some effect in the "a * " and "b*" directions which is taken into account by their corresponding vectors. For example, if the initial paint has the same hue as the target paint but is more saturated a combination of black and white will decrease saturation, while not appreciably affecting the hue. The ratio of black to white would depend on whether the initial paint color is also lighter or darker than the target color.
  • the refinisher With a rendering of both the predetermined target paint color P and the candidate refinishing paint color I on the screen 26 of the monitor 22 the refinisher is able to make an assessment as to the acceptability (in the sense of a color match) between the two. If it were felt that the initial candidate refinishing paint color I is sufficiently close to the predetermined target color P the color selection process would be complete.
