Yes, it's fine. An array in SCALAR CONTEXT returns its length -- the
number of elements it contains.

It never happens because "#hello" and "#goodbye" have the same NUMERIC
value, 0. You want to use string comparison here:
print "dup\n" if $color_dup eq $color_choice;
If you were using warnings (via the -w switch, or the 'use warnings'
pragma in Perl 5.6) you'd be told you were using a string in numerical
context.
