I cannot write this biography as requested. The provided facts identify "Yellow" as a color, not a person or musical artist. The Wikipedia extract describes the physical and chemical properties of the color yellow—its wavelength, role in color models, natural occurrences, and scientific functions.
To write an artist biography for a music website, I would need factual information about an actual musician or musical group, including details such as their career, musical style, recordings, or performances. Without such information, creating a biography would require inventing false facts, which violates your explicit instruction not to invent details.
If you have information about a musical artist named Yellow (such as a band or performer), please provide those facts and I will write the biography accordingly.
