Abstract (en)

[origin: WO2006052556A2] Renderings of a target paint color and an initial candidate color formed from a combination tints T<SUB>1</SUB> through T<SUB>n</SUB> are displaying in respective first and second fields of a video monitor. Upon the selection of one of the tints the display in the second field of the video monitor is updated to display a rendering of a first updated candidate paint color. The first updated candidate paint color is compared to the target paint color to determine an acceptable color match. If, based on the comparison, the color match is unacceptable, the same or a different tint is selected. The color value of a subsequent updated candidate paint color produced by the addition of a predetermined adjustment quantity of the selected tint to the immediately preceding candidate color is recalled from a memory location determined in accordance with the immediately preceding candidate color and the selected tint. The subsequent updated candidate paint color is displayed in the second field. This repetition continues until an acceptable color match is achieved or for M number of iterations, where M is an integer greater than 1, whichever first occurs. The number of adjustment quantities of each tint added to the initial candidate color to produce the last updated candidate color is tabulated. A paint is mixed by adding the tabulated number of adjustment quantities of each tint to a predetermined quantity of a paint of the initial candidate paint color.
