Ultra Melon

Ultra Melon is a colour grade in FRCTL, the browser VJ studio. Watermelon rind green into melon pink with cyan seed sparks.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What Ultra Melon does

Rind green shadows lift to pale pith, then melon pink takes the mids and upper tones. Seeds works off the channels rather than brightness: anything where blue outweighs red flips toward cyan, so skies and the demo art's teal get cyan sparks inside the pink. Rind spreads pith into the darks, Flesh pulls the pink lower.

Using Ultra Melon

Where it works
Summer drops, fruit-bright social clips and loud cover art. Unlike Mango Riot or Tangerine Jet, the cyan follows cool colours in the source, so a blue sky or teal light stays a separate accent instead of joining the ramp.
With the music
The shader has no audio input. B8 hats on Seeds makes the cyan sparks flicker with the hi-hats, and B2 sub bass on Flesh swells melon pink through the frame on drops.
Starting point
Rind at centre, Flesh three-quarters, Seeds a quarter, then raise Seeds until blue areas start showing cyan.
