Some of the CSS support charts on the web provide information on this;
I have found two that claim that some user agents support these values:

* According to <http://www.richinstyle.com/bugs/table.html> (navigate to
the heading "color referencing methods") claims that "UI colors" are
supported by "Moz5", Internet Explorer versions 4 and 5, not supported by
Opera 3.6 and "destroyed" in Netscape Navigator 4 and Internet Explorer 3
(you can see it's an old chart ;-) ).

* According to <http://www.webdevout.net/browser-support-css#css2units>,
UI colours are also supported by Internet Explorer 6 and 7, by Firefox2
and by Opera 9.

(I have never seen these units "in the wild".)

Best regards,

Christophe
