Abstract
Method and apparatus for matching a selected color with predetermined available paint colors wherein a portable color meter is used to analyze a selected color and store chromaticity data representing the hue, chroma and brightness of the selected color. That stored chromaticity data is coupled to a computer which compares it with stored chromaticity data in the computer representing available color formulas and then selects one of the stored paint formulas most closely matching the chromaticity data representing the selected color.
Claims12
A method of matching a selected color with predetermined available paint colors comprising the steps of:
- a. using a portable color meter to analyze said selected color and store chromaticity data representing the hue, chroma and brightness of said color,
- b. coupling said chromaticity data in said portable color meter to a computer,
- c. storing a plurality of available color formulas in said computer,
- d. storing chromaticity data in said computer representing hue, chroma and brightness of each paint designated by each of said stored available color formulas,
- e. comparing the chromaticity data received from said portable color meter with the stored chromaticity data representing each of said stored available color formulas to find the closest match, and
- f. selecting the stored color formula represented by said chromaticity data found to be said closest match thereby matching said selected color.
Apparatus for matching a selected color with predetermined available paint colors comprising:
- a. a portable color meter for analyzing said selected color and storing chromaticity data representing the hue, chroma and brightness of said selected color,
- b. a computer for storing a plurality of available paint formulas and storing chromaticity data representing the hue, chroma and brightness of each paint designated by said stored available paint formulas,
- c. means for coupling said stored chromaticity data in said portable color meter to said computer,
- d. means in said computer for comparing said selected color chromaticity data with said stored chromaticity data in said computer representing each paint designated by said stored available paint formulas to find the closest match, and
- e. means for selecting the one of said stored available paint formulas represented by a said closest match chromaticity data thereby matching said selected color.
