make one letter in a button a different color than the rest

[codeone]

Anyone know how to make just one letter inside a button a different color from the rest something like this:

<grey>P</grey>rint

get it? I bet you do, anyhelp would be great!

I think it has something to do with this:

<style type=&quot;text/css&quot;>
p:first-letter{
float:left;color:blue
}
</style>
<p>

</p>

thats great but I need it to work with the text inside of a button.

Thanks
