Another kind of bad thing is when you see a pen online, the photos make it look so lovely. Then when it arrives, it doesn't seem to match that. I got one pen, in a purple color, but inside it looks dark, almost black. It needs very good, bright light to show off the color, plus the reds and blues that are in it.
At night all cows are grey... in Germany they are even black! The colour receptors in our eyes work only within a limited range, once the light strength is below a certain level, all we see is grey. Try it.
