If your not sure cooler blues usually look darker. Most warms are titled or have Cerulian in the name but not always. It was touched up with a close value but a cool temperature blue and it shows. There's a Jokers for sale in the adds with some patch touchup's (in Florida) and that's clearly what happens. Some people won't get that but it really shows in blues in this value range. I'd start with the golden grab it, and take it to the cheap hobby isle and compare colors.
You'll also find acrylic paint in the hobby area, its usually much cheaper. Golden Acrylic's are expensive and usually in the painting isle of Michaels or Hobby Lobby.
