One color scheme I would NOT want to see is "invisible". I have a hard enough time finding my phone sometimes as it is.
Decades ago in high school I worked in a now defunct department store and one of the jobs I had was to clean and prep aquariums for the periodic tropical fish delivery. After the delivery day, I had to change the labels/prices of the fish if they prices changed or the type/size of fish changed. One tank was empty, so I made a label "invisible flying fish, $3.49". It was fun to see folks stare and point to the imaginary creatures! Not sure if any were sold. Coincidentally enough, I was never tasked to do fish tank duties ever again.
