Making a solid color image in VIP

What method would you use to output an image of a solid color? This color wouldn't need to change very much. All my objects are in SOPC builder. Hardwiring or just filling memory locations with...

Inputs to an Alpha Blending Mixer module (with 2 alpha-blended layers)

din0: 3 channels 8-bit progressive RGB in parallel (actual video input)

din1: 3 channels 8-bit progressive RGB in parallel (a solid color)

alpha0: 1 channel 8-bit single color plane (fixed at 0 (opaque))

alpha1: 1 channel 8-bit single color plane (custom signal, derived elsewhere)

I'm not sure how to fix an alpha channel at opaque (alpha0) or fix the 3 channel video (din1) at a specific color.

This would be exceedingly easy if I had access to the code of the Test Pattern Generator Megafunction, as I could just strip it's functionality down. I can see some documentation on how to use the SOPC editor to wrap a circuit, but I have no reference design on what the circuit should look like inside. It would obviously just need to respond with a fixed bit sequence whenever asked via the Avalon-ST Video standard.
