...sometimes, people that don't even have a clue on html are suggesting things that are not existing... that's why... (people sometimes are helping evil forces)
so here are the possibilities:
HTML Code:
<span style="color:#ffffff;">Your Text</span>
<font color="#ffffff">Your Text</font>
logically, the "</color>" thingy is useless... a ending tag have to close a starting tag... </this> will close <this> tag...
