Chromatic Aberration Cute Pun Mug

Crow-matic aberration / chromatic aberration pun featuring a cute crow! Different colours of light have different wavelengths. Chromatic aberration is the effect you see when a glass lens refracts light such that the colours don't meet at the same focal point, resulting in a colour offset effect (can be seen in some photographs - you might for example see red lines to one side of an object and blue lines to the other side). The effect is most pronounced with red light (long wavelength) and blue light (short wavelength).
