Thanks for the compliments! The gray parts are indeed gray, and the yellow and gray are auto paints from a spray can. I cut a stencil by hand for the squiggle, and used it as a mask for the black color, also a spray can. (I'm a graphic designer, and a squiggle is standard shorthand for 'headline goes here.') Then I sprayed the whole thing with a 2-part highly toxic this-stuff-will-kill-you epoxy gloss called "Glamour." Up close, it ain't perfect, but it's pretty good for an amateur.
