Wrong CSS warning ?

Hello,
When trying to validate this page <http://francisiegel.fr/fr/index.html> 
with Unicorn, the CSS validator is warning me that #english in 
http://francisiegel.fr/style.css doesn't have a color. But it does have 
one :

#english,

#french {

display:block;

margin: 75px;

text-align:center;

text-decoration:none;

color: black;

background-color: inherit;

font-family: sans-serif;

font-size:large;

}


Regards,
