Roses Are Red, Roses Are Blue

Roses are red Roses are blue Depending on their velocity relative to you.

Two stylized roses are shown, one red and one blue, above a diagram of waves moving toward an observer and a gray object. The joke twists the familiar “roses are red, violets are blue” rhyme into a physics reference: an object’s apparent color depends on its velocity relative to the viewer, illustrating the Doppler effect. It is used as a nerdy science reaction to jokes about color, motion, or relativity.
