The disclosed systems and methods emphasize driving LEDs in series and in parallel with the same LED driver chip and a single inductor. For creating overlap, the systems and methods of LED color overlap disclosed herein take advantage of the fact that green and blue LEDs have the same voltage. Thus, green and blue LEDs can be driven in parallel as needed. LED suppliers can screen parts for sufficiently close voltage matching between green and blue LEDs. This is especially true when using green LED die based on a blue die with a green phosphor. Cyan may be produced by driving a green LED and a blue LED in parallel. White may produced by driving a green LED and a blue LED in parallel and a red LED in series with this green and blue parallel pair.
