Method for acquiring a preferred memory color of object and standard color chart of preferred memory color

A method for acquiring a preferred memory color of an object, comprising the following steps:

• S1, acquiring an original image of a target object and a spectral reflectance distribution curve of a surface color of the target object;
• S2, rendering the original color corrected image to obtain a plurality of experimental images, wherein the color indexes of all experimental images are covered within a set range, and the colors of the experimental images are capable of reflecting the color of the target object;
• S3, acquiring evaluation data of a memory color preference based on the experimental images, wherein the evaluation data comprises a preference rate Pv of a subject for each of the experimental images;
• S4, obtaining a coordinate value of the preferred memory color by using an elliptical memory color model according to the evaluation data, wherein the ellipsoid memory color model is configured to establish a relationship between the evaluation data and the coordinates of memory colors of the experimental images in color space, so as to obtain a preferred memory color ellipsoid, and a center point of the preferred memory color ellipsoid is the coordinate value of the preferred memory color;
• S5, adjusting a color coordinate value of a color patch to be consistent with the coordinate value of the preferred memory color, and adjusting the spectral reflectance distribution curve of the color patch to be consistent with a shape characteristic of the spectral reflectance distribution curve of the surface color of the target object;
• and
• S6, taking the color of the color patch as the acquired preferred memory color of the target object.
