[0046] 1. Overall design

[0047] The general design of the present invention is as follows figure 1 As shown in the flow, the whole includes two parts, one is to obtain the inverse function of the proportional mixing, and the other is to use the inverse function of the mixing ratio to complete the calculation of the color mixing ratio.

[0048] Second, the calculation of the proportional mixed inverse function

[0049] 2.1 Pigment color preparation:

[0050] Select the three primary colors of the pigment to mix by volume ratio. Here is an example of solid pigment - ultra-light clay, three primary colors yellow, red and blue, as well as white and black, using these five colors can be mixed into most colors. The three primary colors determine the hue (H) of the pigment color after mixing, change the saturation (S) by mixing black pigment, and mix the brightness (V) of white pigment. The mixing of the three primary colors at the same time will turn gray-black, and the presen...

Abstract

The invention discloses a method for matching a pigment color mixing ratio. The method comprises: S1, acquiring a to-be-tested pigment image; S2, carrying out pretreatment on the to-be-tested pigmentimage to obtain an RGB value of the to-be-tested pigment image; S3, carrying out pigment color collection on the to-be-tested pigment image after pretreatment; S4, carrying out color space conversionon the collected pigment color, that is, conversion from RGB to HSV; S5, with the HSV, calculating ratio mixing functions of all channels of hue (H), saturation (S), and brightness (V); S6, on the basis of the obtained ratio mixing functions, calculating inverse functions; and S7, according to the inverse functions, inputting a to-be-mixed color and a target color and obtaining a color mixing ratio, With the method disclosed by the invention, color collection is completed and the ratio mixing rule of a pigment is obtained; and with the inverse functions of the ratio mixing function, a ratio ofthe target pigment to the to-be-mixed pigment is obtained.

Description

technical field [0001] The invention relates to the technical field of pigment mixing, relates to a mixing method of solid pigment ultra-light clay, and in particular relates to a method for matching the color mixing ratio of pigments. Background technique [0002] At present, there are many studies on the mixing of shades at home and abroad, but there are few studies on the mixing of pigments. The main reason is that all pigments contain pigments and chemical substances, and the color mixing is more complex due to the influence of different chemical substances. , including the mixed hue, saturation, brightness, and transparency of liquid pigments, which are hard to find. In color mixing, most people use experience to estimate the proportion of pigments to be mixed according to the target color. It is easy to match the wrong proportions, or even mix the wrong colors, resulting in a serious waste. [0003] As a colored clay, ultra-light clay has the characteristics of vario...
