Hi,
Just one note here...you are missing two colors...one of which is 'dark'.
You have red, you have green, but no 'off', and no 'amber'.
If you drive it with a bi phase circuit like that you can never turn it off
unless the inverter is linear and has a gain of 1, or you have some way
to turn the power supply off.
If you use two drivers you can then control each LED almost independently,
so you can get red, green, dark, and by using a square wave of 50 percent
duty cycle you can also get amber. If you care to change the duty cycle
of the square wave you can get other in-between colors.
