I think that it is the responsibility of the user to 
cover both background and foreground colors if the viewer 
customizes the browser.

I've never understood why the background property 
doesn't inherit. I'm sure there must be a reason, but 
I really can't think of any.

True

And while we're on the subject of colors, I think it should 
be a law (punishable using death by <blink>) that any 
"enhancement" to HTML that changes a foreground color should 
also allow for the specification of a background color, and 
vice versa.  I'm thinking specifically of BGCOLOR in table 
cells, and COLOR in <FONT>. I don't want to use a Bgcolor 
that contrasts too much with the body color because otherwise, 
I'll have to use <FONT COLOR=""> for the text inside the 
table. But there are some browsers that understand 
<FONT COLOR=""> yet don't honor the BGCOLOR attribute in 
<TD>.  

And I won't even get into the problem of users 
selecting "always use my colors" and yet the browser uses 
the colors specified in <TD BGCOLOR> and <FONT COLOR>.

Granted, these attributes should be specified using style 
sheets anyway, so perhaps the problem will just go away. 
But even in stylesheet land there is a problem with background 
colors in <link>'ed stylesheets. (Fixed in the Mac verion 
of IE, thankfully.)
