The pigments available for paint selection are divided into 9 basic colors, such as red, orange, yellow, green, purple, blue, white, black, and metallic gloss. Different wavelengths present different hues, the same wavelength range, and different sensitivity to tonal changes.
, the lightness of colors can vary with the purity of the hue
. Therefore, in the design of colored coatings, pigment selection is very important, should be based on a variety of pigment color labels for deployment. In addition, the physical properties of the selected pigments such as particle size, coloring force, covering force, suspension, spinlight resistance, heat resistance, etc. should be considered.
7 principles of color matching
(1) When color matching paint, as far as possible, choose red, yellow, blue, white, black five basic colors for color matching
;
(3) In the specific color matching, as far as possible to choose different lightness of the same color color pigment color, so that
can form a primary and secondary, light and dark coordination of the paint color;
(5) When coloring a coating, there should be no reaction between coloring pigments, such as lead, copper, mercury pigments mixed with sulfur pigments, the color darkens;
(6) In the color matching of the coating, to improve the brightness of the color of the coating, a small amount of dye can be added, to improve the color purity of the coating, you can add a moderate amount of white pigment covering the large amount of noise in the coating;
(7) in the same coating formulation system, coloring pigment varieties should not be too many, so as not to bring into the noise, so that the paint color darkened.
