How are color pigments classified?
Color pigments and ceramic pigments are the foundation of printing and painting procedures. They impart color to objects by absorbing and reflecting light in various ways. To order ceramic pigments researchers concentrate on the frequencies of light that they absorb and reflect.

What are color pigments?
Color pigments are particles that are utilized to make colors in daily existence. There are maybe one or two kinds of color pigments, and they can be grouped in view of their properties. Type I color pigments are the most well-known and are comprised of little particles. These pigments can be combined as one to make various colors, and they have many purposes remembering for paint, ink, cosmetics and beauty care products. Type II color pigments are comprised of bigger atoms and can be more challenging to combine as one. They are utilized in paints and coatings, and they frequently have a more brilliant variety than Type I pigments. At last, colorless or transparent colorants are utilized to make pigments that don't reflect light. They are many times utilized in polymer materials and adhesives.

The three types of color pigments: organic, inorganic, ceramic, iron oxide and mixed
Color pigments are classified according to their type of pigment: organic, complex inorganic color pigments, and mixed. Organic color pigments are made from natural resources like plants or minerals. Inorganic color pigments are made from man-made materials like metal oxides or plastics. Mixed color pigments contain both organic and inorganic pigments.
Classification of color pigments according to their physical properties:
Color pigments are arranged by their actual properties. This incorporates their hue, chroma, lightness, and saturation. Hue is the name of the color, while chroma and lightness depict how light is ingested and reflected. Softness is estimated on a scale from 0 to 100 percent, while saturation portrays how much color is available or present in a pigment.

D. Pigment uses
A. Pigment solubility:
1. Inorganic pigments are generally more soluble in water than organic pigments. This is because organic pigments contain carbon-based molecules that are more tightly bound to one another, making them less able to absorb water.
2. Soluble pigments can be divided into two groups based on their chemical structure: lipophilic and hydrophilic. Lipophilic pigments are attracted to oil and water based surfaces, while hydrophilic pigments are not as strongly attracted to either surface and can be dispersed in both liquids.
3. The most common way to classify soluble pigments is by their chemical structure: aliphatic hydrocarbons, aromatic hydrocarbons, and terpenes are all aliphatic hydrocarbons, while dyes and phthalocyanines fall into the category of aromatic hydrocarbons.
B. Pigment optical properties
One of the main properties of pigments is their optical properties, which can be arranged by their frequency of light retention. Iron Oxide Pigments can also be ordered by their actual way of behaving, including solubility, viscosity, and thermal stability.
C. Pigment stability
Color pigments are commonly grouped by their dependability. Pigment stability is a proportion of how well a pigment opposes blurring or changing variety under various ecological circumstances. The four principal classifications of pigment stability are below:
1. Non-stabilized pigments: These pigments do not maintain their color under various environmental conditions, such as exposure to sunlight, heat, or humidity.
2. Unstable pigments: These pigments often fade or change color when exposed to light or other environmental conditions.
3. Stable pigments: These pigments usually maintain their color even after being exposed to light or other environmental conditions.
4. Permanent pigments: These pigments never fade and always retain their original color
