I've skinned all my drones for visibility, the neutral DJI colors, and also the Platinum, are very easy for me to lose sight of. The completely un-natural, solid color, neon skins work best for me.
The Solid Color selection in the Artist Filter dropdown at DecalGirl.com has them named Neon Flourescent, and the solid Red and Blue also work for me.
At WrapGrade.jp, they call them Neon. There are also some great looking metallic wraps, but they only look great when the drone's sitting still, or being admired, in good light. When the drone flies away, they show up as grey to me.
Of these two, Decal Girl's skins have fewer pieces and are easier to make a neat job, but they're cut to fit without overlapping, so the edges show a little bit of the drone. I like the look OK. Pieces can be removed if the drone needs repair, and replaced. Decal Girl's in the US and their wraps less expensive.
WrapGrade's skins have more parts, and they're cut to overlap at the edges, so if you follow their map and work carefully it looks pretty close to painted on, with almost none of the drone showing. If the drone needs repair, removing a piece with overlapped edges can easily ruin the wrap. They're in Japan, the wraps are more expensive, and so is the shipping. They're the best look after some practice, very easy to do a sloppy job the first time.
I've tried some of the bright-looking patterns, but at any distance they can turn into camouflage for me, so I've settled on Neon and solid, bright colors.
There are others, but I've used each of these two a few times. When wrapgrade.jp couldn't deliver for the first few months of the Wuhan shutdown, I tried Decal Girl and was pleased.
