Fun Fact of the Day: A bruise or contusion is caused by some kind of knock or bump to the skin. When your body starts to metabolise these cells – literally reabsorbing them – then the bruise will go through a series of colour changes – from red to purple, purple to blue/black, blue/black to green, green to yellow before finally turning a browny skin tone. This colour means the injury is nearly completely healed.
Fun Fact of the Day: Pollen comes in many colors. Though we associate pollen with the color yellow, pollen can come in many vibrant colors, including red, purple, white, and brown.
