Synaesthesia

Red has so much variety. It runs the gamut from moist to salty, sweet to cutting, plush to fiery.

Orange keeps mostly to one track. It can radiate warmth, but sometimes on the radioactive scale. Alarms and sirens often texture it roughly, but it can also sing like peach fuzz.

Yellow, on the other hand, has quite a limited range. It nearly always tastes like sunlight or sounds like a slip-and-slide.

Green spreads from the cool leaves of middle earth to the briny seas of the little mermaid to the sibilant hissings of house Slytherin.

Blue smacks of rain, no matter what hue. However, that rain varies from warm to sharp, quiet to acrid.

Purple wears the crown. It never tastes too noisy or smells too strongly of fluffiness. No matter the form, it always looks beautiful.
