She's naturally dirty blonde, but she dyes it lighter.
her original color is brown but she dyes it like a golden blonde color
It's naturally light brown, but he dyes it black, and usually has highlights in it :D xx

Synthetic dyes offer a wide range of colors, stability, and affordability. They can be easily produced in large quantities and are versatile in their applications across various industries such as textiles, food, and cosmetics.
The first people to use artificial dyes were the ancient Egyptians, who used natural resources to create colored pigments for paintings and textiles. The synthetic dyes industry began to develop in the mid-19th century with the discovery of synthetic dyes like mauveine by Sir William Henry Perkin.
Synthetic dyes have a significant impact on the environment due to their toxic chemical composition and water pollution during production and disposal. They are also linked to health concerns like allergies and skin irritation. Efforts are being made to develop more sustainable and eco-friendly alternatives to reduce the impact of synthetic dyes on the environment and human health.
Different types of dyes are used for different textile fibers based on the characteristics of the fiber. For example, acid dyes are used for protein-based fibers like silk and wool because they bond well with the amino groups in these fibers. Reactive dyes are used for cellulosic fibers like cotton because they form covalent bonds with the hydroxyl groups in cellulose, providing good wash-fastness. Disperse dyes are used for synthetic fibers like polyester because they have low solubility in water and can penetrate the hydrophobic surface of these fibers.
Food colors and inks can contain mixtures of dyes derived from natural or synthetic sources. These dyes are combined in various proportions to achieve specific colors. It's common for manufacturers to use a blend of dyes to create a wide range of colors for different applications.
