RGB to HEX

[Garrett Hylltun]

Rev 2.6.1

Greetings,

Is there a built-in function in Rev that will convert RGB color  
string to a HEX color string?  If no, does anyone know how to do  
this?  I knew how to do this in another language, but am at a loss as  
to how to work it out in Rev.

Thanks in advance,
-Garrett
