L'azul ye ún de los tres colores primarios. Considérase un color fríu y ye l'opuestu al naranxa. L'azul claru tien la llonxitú d'onda más pequeña de los tres colores primarios (unos 470 nm)

Un cielu claru nún día soleyeru ta colloreáu d'azul per aciu de la dispersión Rayleigh de la llume del Sol. Les grandes mases d'agua (H2O) semeyen azules porque la lluz roxo, al puntu de los 750 nm, absórvese con un harmónicu de la vibración O-H. Curiosamente, l'agua pesao (D2O) ye incoloro, ya que la banda d'absorción ye a una llonxitú d'onda más llarga (~950 nm).

L'azul ye complementariu del mariellu.
