Yellow
Yellow me this, Batman! What's yellow and yellow and yellow all over?
That's right!
Yellow!
Yellow is the third color in the rainbow, the second color in printers, and the fifth in Elements. In color theory, it represents happiness, sunshine, urine, sulfur, warning signs, bananas, disease, lightning, and bile. Certain flowers, such as sunflowers and dandelions, are yellow. Yellow can hold bombs, be thrown higher, resist electricity, and dig faster. For a real life example, please press control and p on your keyboard.
