    \$\begingroup\$ In the color string and the test, change Grey to X, since it's not used. You'll gain 6 bytes. \$\endgroup\$ Commented Mar 19, 2018 at 11:09

    \$\begingroup\$ Reverse the for's condition to need no parenthesis: x!=$b=$a[array_rand($a)]. BTW, ?> terminates a statement, no need for ; in front of it. \$\endgroup\$ Commented Mar 19, 2018 at 11:30
  • \$\begingroup\$ @manatwork Ohh, nice! I'll update my answer now! \$\endgroup\$ Commented Mar 19, 2018 at 11:33

    \$\begingroup\$ You can save a few more bytes by not including x at all and using $b=$a.. as the condition and using rand(0,7) instead of array_rand. You can remove the newline between ?> and Grey duck too. Also your TIO link still had full tags, you can add -d short_open_tag=on to flags to get that working! :) \$\endgroup\$ Commented Mar 19, 2018 at 12:07
