How is color paper made, and what materials are used to make it?

Color paper is made by adding pigments or dyes to a pulp mixture during the papermaking process. The materials used to make color paper are similar to those used to make traditional white paper, but with the addition of colorants.
Here is a general overview of how color paper is made:
Raw materials: The primary raw material used to make paper is wood pulp, which can come from a variety of sources, including trees, recycled paper, and agricultural waste. Other additives, such as fillers, sizing agents, and brighteners, may also be added to the pulp mixture to improve the quality of the final paper.
Bleaching: If the desired color of the paper is very light or white, the pulp mixture may be bleached using chlorine or other chemicals to remove impurities and create a uniform color.
Adding colorants: Once the pulp mixture has been prepared, pigments or dyes are added to create the desired color. The amount of colorant added will depend on the intensity of the desired color and the thickness of the paper.
Forming the paper: The colored pulp mixture is then poured onto a screen or mold, where it is shaped and pressed to remove excess water and form the paper.
Drying and finishing: The paper is then dried and finished, which may involve further treatments to improve the texture, strength, and appearance of the paper.
The specific materials and processes used to make color paper can vary depending on the manufacturer and the desired quality and color of the final product. Some color paper may also include additional features, such as textures or patterns, which are added during the papermaking process.
