Blue light has a shorter wavelength than red light. Shorter wavelengths have hgher energy levels. And can be calculated from Plancks constant: Therefore Blue light (470nm) has a more energy than Red light (700nm) and a transition that releases Blue light will be at a higher energy level than one that releases Red light.
