Metal complex dyes are considered environmentally friendly because they have a high level of color fastness, meaning they do not easily fade or wash out. This results in less dye being released into the environment through wastewater. Additionally, metal complex dyes are more efficient and require less dye to achieve the desired color, reducing the overall environmental impact of the dyeing process. Lastly, these dyes are often more biodegradable compared to other types of dyes, further minimizing their environmental footprint. **
