That should translate OK.  As with yours, it changes only red, green or 
blue at a time, and thus will vary in intensity in ways not intended.  
The blue-purple looks like it goes too purple to me.  The function does 
attempt to put an envelope over the whole thing that is probably 
related to sun intensity and eye response.

See how it looks.
