Hi nicolas Thanks for the information of color I was also looking for it. The other packages that extended color used 1/1000 so I followed the pattern. I was thinking that I should use something like "printInexactlyOn:" Now (too early for my brain to work) but I'm wondering the different between round and roundUpTo: I remember that once we discuss having an exact method where we can pass the precision.
