So very true. A pilot in a club I used to belong to built an Astro Hog and finished it in light and dark blue in a Fly-Baby type scheme. It was drop-dead gorgeous. He took off and it vanished. I'm "color deficient" (according to the Marines) and I could barely make it out and had no feel for orientation . Unfortunately, the pilot was worse than me. He handed over his Tx and another pilot landed it without event - said he could see it just fine. Next time we saw it it was yelow and red.
