Next time you have a party at work or home, try this and see for yourself.
The first time, put these common/regular napkins in a bunch for the guests to use.
Watch them abuse these napkins, just pulling them out as they please, in any numbers. Most people will take more than one. They will trash this napkin without care and get more as needed.
The second time, use these instead. Nothing really fancy here compared to the previous napkin - just a different, bright color.
Watch the difference this time. People will treat them as special, being careful to just pull one at a time. They will also preserve this napkin longer.
People automatically assign importance when something appears different or fancier than what they are used to.
Unfortunately, This is also the same principle where well dressed people are usually treated better.
