I have a new client with an interesting product. They are driving
large quantities of LEDs (in the hundreds, with future products to
be in the thousands) in banks of red, blue, and green (with, of
course, different voltage/current requirements for different
colors). They want be able to dim each color using a microcontroller
-- PWM is OK as long as the human eye doesn't see any flicker.

Fascinating. I know someone (family actually) intending to do something
very similar.

For a one-off like that. you might consider one of the demo
boards (they have DB in the paty number) here:
