I layed all my hand tools out on a tarp and sprayed one side with "day glo" orange paint. Also I did the same with my garden and lawn tools. It sure makes them easier to find. The paint might wear off eventually but enough stays in the nooks and crannies to identify them.
As far as my bench and floor tools go, My shop is in my basement so I have them insured.
OBTW, I saw an episode of This Old House back in the day that was filmed, I think, on Nantucket Island, MA, USA. They had a female electrician on the show and she had painted all her tools Pink. She wore a pink tee shirt, for obvious reasons. Her rationale was that no testosterone infested male would dare use a pink tool. Cute
