Fading with limited colors

How do you make a nice fade from white to black with a limited set of colors?

I'm writing a "demo" for virtual machine i have designed and written. It has 4096 colors and i need to do a nice fade from white to black. Since there is only 16 different levels of gray i would like to extend this by using some more colors.

I have seen nice fades from white to black on the c64 using far fewer colors.

Is there any general function for doing this in arbitrary color spaces.?

You could calculate the brightness of the available colors:

RGB: brightness = (R + G + B) / 3

Or use other color models (HSL, HSV etc.): http://en.wikipedia.org/wiki/HSV_color_space#Lightness

and order the colors by brightness.

If you are free to generate any color, create/generate a nice palette of colors and, again, order by brightness.
