I have a set of four mugs that come from Dollar General maybe 5 years ago. Blue, red, green and yellow with roosters on them....the insides are matching colors. Even though they are made the same, there is something about the yellow one that I will 98% of the time grab. My husband uses tiny mugs that he has had so long they are stained and chipped, but he won't drink coffee from any other mug. To each our own I guess!
