FIG. 1 illustrates, by way of example, a diagram of an embodiment of a color space divided into hybrid 108 and PWM 102, 104, 106 driving scheme regions. In the embodiment of FIG. 1, the color points are realized by a controller driving LEEs using either a hybrid 108 driving scheme or a PWM 102, 104, 106, driving scheme. Since the hybrid 108 driving scheme is more energy efficient, if the color point can be generated using the hybrid 108 driving scheme, then improved energy efficiency can be realized by driving the color point using the hybrid driving scheme. The hybrid 108 driving scheme, however, cannot be used to produce some colors that can be produced using the PWM 102, 104, 106 driving scheme.
