i can try translate() function , but it requires to know what i want
to translate and what i want to translate it to.In my case since i
dont know what would be the text in the color ellement, I reckon
translate() wouldnt be of much help .

I think that you're misunderstanding how the translate() function
works. [...snip...]
So the translate() function can be used to translate words from
lowercase to uppercase, as long as it's a character-by-character
conversion that you're interested in (e.g. you don't want 'ß' to
become 'SS').

The XSLT Standard Library provides a general solution that handles
international case-conversion, like the 'ß' to 'SS' case described
by Jeni.  See http://xsltsl.sf.net/
