Cool effect

Prism Pulse

Prism Pulse is a colour grade in FRCTL, the browser VJ studio. Powder blue and ultraviolet split against rose and amber.

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 Prism Pulse does

Splits the frame twice. Cool pixels grade from powder blue to ultraviolet and warm pixels from rose to amber, then brightness hands over from the cool side in the shadows to the warm side in the lights, finishing on pale gold. Burst sets how early that handover happens and how much gold lands on top, while Cool and Warm deepen each side.

Using Prism Pulse

Where it works: Split-toned cover art and headline shots that want indigo shadows and amber lights without the stock teal-orange look. Skin reads rose and amber, so it's far kinder to faces than Thermal Vision.
With the music: No audio or clock drives it internally. B1 kick on Burst floods the frame with amber and gold on every kick, and a beat-synced LFO on Cool pumps the shadows between powder blue and ultraviolet.
Starting point: Cool three-quarters, Warm at centre, Burst a quarter, then raise Burst until amber reaches the upper mids.

Controls

Cool: Powder blue to ultraviolet cool split.
Warm: Rose to amber warm split.
Burst: Luma handoff and gold final burst.
