Contrast. I try to never place light items on light surfaces, for instance.
Also, putting things down “real quick” to have your hands free for a moment is strictly forbidden! Put them in your pocket, in your mouth, or even walk all the way back to place them in their usual spot but do NOT just put them down wherever you stand. This rule alone has saved me hours of anguish.

What is a light surface?
Sorry, I was probably a bit lazy there. Light-colored surface was what I meant. Same with the item placed atop it.
