Two problems:
a) attron passes the color packed in a chtype, which limits it to 4
bits.
b) the "right" interface would be something like wattr_set, but unless
you have compiled ncurses using the extended colors (or perhaps using
the ncurses6 packages that I upload occasionally), you won't get
that.
I covered some of that in my faq:
