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
