You can certainly make leds appear to fade by flashing them very fast.
Unfortunately most leds that do green, amber and red are actaulyl just
a green and a red led in one, which looks amber when both are on at once.
So it has 4 states available: black, green, amber, red.  What neat stuff
can be done with 2 x 12 x 2bits?
