+<p>Your website probably has a color-scheme.
+<span style="color:#090; background:#FFF;">Green on white</span>,
+<span style="color:#A0F; background:#FF0;">purple on yellow</span>,
+whatever. When you give users the ability to style their content, you may
+want them to keep in line with your styling. If you're website is all
+about light colors, you don't want a user to come in and vandalize your
+page with a deep maroon.</p>
+
+<p>This is an extremely silly feature proposal, but I'm writing it down anyway.</p>
+
+<p>What if the user could constrain the colors specified in inline styles? You
+are only allowed to use these shades of dark green for text and these shades
+of light yellow for the background. At the very least, you could ensure
+that we did not have pale yellow on white text.</p>
+
+<h2>Implementation issues</h2>
+
+<ol>
+<li>Requires the color attribute definition to know, currently, what the text
+and background colors are. This becomes difficult when classes are thrown
+into the mix.</li>
+<li>The user still has to define the permissible colors, how does one do
+something like that?</li>
+</ol>
