Wayne, I support you on the ability to change font and color.

The ability to change color is essential to my use of web pages.

An icon that depends on background color to be visible is using color to convey meaning.
A presentation that depends on a background image to make font visible is using color to convey meaning.
Background images were never created to act as cashes for icons. Using sprites in background images is like using a heading because you like the style of the element.
We are being blocked from accessibility because of an identifiable list of practices that are kludges.
Testability of color substitution is trivial.  Setting save  color choices with a wide domain of choice is trivial.  There is not reason to deny users access to the color of their choice.
If color is taken off the table I will prepare an appeal to the AC. I have enough data to prove my case

Ach, I shouldn’t reply from my phone, I had meant the test should be:

“Change the colours to black and white. Where the foreground text is dark use white on black, or if the foreground text is light use black on white.”

This would be a test to find issues as a proxy of what the user does, it is not the user requirement. I think that would highlight any issues people encounter?

I can’t think how to get that into SC text as a bullet though… perhaps:

* Colours can be adapted to a high-contrast colour scheme such as black and white.

Although not everyone wants high-contrast the ability to change it is there, easy to test, and clear on the requirement… I hope.
