    摘要： A computer-implemented method for displaying on a color display device a realistic color of a paint coating comprising the following steps: (A) identify L*, a* b* color values at least three different angles for a paint coating from a data base; (B) convert the at least three angle L*, a* b* color values to tristimulus X, Y, Z values; (C) develop continuous function equation for each tristimulus X, Y, Z values vs. aspecular angle via computer implementation and calculate the range of angles to be displayed; (D) calculate a range of aspecular angles required to display the object; (E) calculate R,G,B values from tristimulus values over the range of aspecular angles and determine maximum saturation of R,G,B values and bring into range allowed by color display device; (F) determine statistical texture function of paint coating to be simulated; and (G) apply statistical texture function to the R,G,B values of step (E) and display color pixels on color display device to show realistic color of paint coating.

    摘要： The present invention is directed a computer-implemented method for determining a color matched repair paint formula, wherein color characteristics of a target color to be matched are identified, inputted, and processed in such way as to enable a visual display of the target color, then alternate color(s) is/are selected from a color database based upon color characteristics of the target color to be matched, then subsequently processed and visually displayed thus enabling comparison of the alternate color(s) with the target color; and finally, a desired alternate color is selected and a formulation determined thereof. Further, the target color may be superimposed over an image of a vehicle to be repaired, and alternate candidate may even be superimposed over the target color in the area of the vehicle to be repaired, in order to assist the user with selecting the best match.
