Advertising color is a viscous color paste made by mixing coloring pigments with glue and water. Its coloring ability is to use the coloring pigment in the pulp to adhere to the surface of the wood to color the wood. Advertising colors can be bought everywhere, and they are more convenient, so a little advertising color is often added to the base color. However, the advertising color should not be added too much, so as not to cover the wood grain and affect the appearance. Commonly used advertising colors include bright red, medium yellow, ochre, and dawn brown.
Ink is an auxiliary color for dark colors. Adding it to the dye solution can make the color black, such as adding ink to the yellow sodium powder solution to get dark brown; adding ink to the acid scarlet solution to make deep red or purple. Ink is generally not used alone, and good first-class ink is used, and stinky ink that is dim in color cannot be used.
