Dear Stata users,

I have installed the -colorpalette- wrote by Ben Jann, and I remenber that it run successfully before. I run it today but fails. I reinstall -colorpalette- and -colrspace-, but the problem still exists. Below is the information:
Code:
. version
version 16.0

. colorpalette
function pexists() not declared in class ColrSpace

(error occurred while loading colorpalette.ado)
r(3000);
