WebbBromophenol blue is also used as a dye. At neutral pH, the dye absorbs red light most strongly and transmits blue light. (Its peak absorbance is 600 nm at a basic pH of 12.) Solutions of the dye, therefore, are blue. At low pH, the dye absorbs ultraviolet and blue light most strongly and appears yellow in solution.
