Checkerboards are cool, I love 'em, but they blend in. For orientation at a normal distance, 3" or 4" stripes front-to-back with a similar gap of white in between works well. Black, red, and I have used neon pink or green left over from another build and they show up very well.
I did the bottom of my Ultra Stick 40 ARF in 1.5" red/white checkerboard (ultra cote IIRC) so it would be at least a bit different from the other US ARFs. Dang things are as common as Cubs. It blends in, but looks good doing close-in knife edge passes.
