On the board below are two drug bottles, one having drug " D " and the other having drug " L ". Which one is darker ? Everyone will say that drug D is darker than drug L . In reality, both bottles have EXACTLY the same shade. Drug D is not darker ! Drug L is not lighter ! (see proof below)
Now I am sure that you will not believe that drug D and drug L have exactly the same shade. Here is an easy way for you to see for yourself that both have EXACTLY the same darkness. Take a piece of scrap paper.
Tear two holes approximately where you expect the two drug bottles to be.
Hold the paper with the holes over the computer screen. You will be amazed to see that both drugs have EXACTLY the same shade. Drug D is not darker than drug L !
Try it out now. Is drug D darker than drug L ?
