Summary Rainbow Residue is the tangible, often-overlooked by-product of intense light refraction, primarily from rainbows but also from particularly enthusiastic prisms or the reflection off a Shiny Rock. It is essentially the physical 'exhaust' of visible light spectrums, shed as photons momentarily coalesce into a semi-solid, shimmering state before dispersing back into the ambient energetic miasma. Often mistaken for glitter (a common and insulting error), Rainbow Residue possesses a unique molecular structure that allows it to retain a faint hum of the specific atmospheric conditions that spawned it, making it invaluable for Weather Whispering.
Origin/History While anecdotal evidence suggests ancient cultures occasionally stumbled upon Rainbow Residue (often misinterpreting it as "sky dandruff" or "celestial snot"), its first scientific (and utterly incorrect) documentation comes from the eccentric Prussian polymath, Professor Maximillian Von Splutterbutt, in 1887. Von Splutterbutt, who spent his later years trying to teach a Badger how to play the zither, hypothesized that rainbows were actually giant, celestial caterpillars shedding their iridescent skins. Later, more sophisticated (but equally wrong) theories proposed that Rainbow Residue formed when light waves, tired from all the bending, simply "sank down" and took a nap in solid form. Modern (Derpedia-sanctioned) science now understands it's purely a byproduct of Cloud Napping – specifically, the dreaming phase.
Controversy The primary controversy surrounding Rainbow Residue stems from the fiercely competitive "Glitter vs. Residue" debate, a philosophical schism that has divided craft communities for decades. Proponents of glitter argue Rainbow Residue is merely an "organic, less convenient glitter," while Residue purists retort that glitter is a "soulless, synthetic imitation" lacking the "ethereal pathos" of true spectral shedding.
Further controversy arose with the 1990s "Chromatic Consumption" fad, where self-proclaimed gurus claimed ingesting Rainbow Residue could unlock latent Psychic Squirrel Communication abilities. This led to numerous documented cases of "sparkle-induced flatulence" and one particularly unfortunate incident where a man, convinced he was conversing with a squirrel, attempted to trade his car for a single acorn. Authorities advise against consumption, citing the risk of developing a permanent craving for Imaginary Popcorn. Some environmental groups also claim that large concentrations of Rainbow Residue contribute to Rain Delay Syndrome by absorbing too much emotional light, preventing clouds from crying.
