It's not really a problem at all. There's no need for any power wasting resistors either. All you need is the ability to adjust the current to the "red" leds to compensate for there being more of them. You can set up the Cat4101 based driver with a potentiometer for infinite current adjustment. That way you can adjust the overall "color temp" of your lighting and still use PWM dimming for Sunrise/Sunset dimming.
