Berry Nocturne is a colour grade in FRCTL, the browser VJ studio. Grape lows through magenta berry into violet and rose.
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.
Shadows fall to grape, then brighten through magenta berry into a rose-pink top. Violet works differently: it keys off the source's blue channel, so skies, denim and cool light turn blue-violet while reds and skin stay berry and rose. Raise Grape to pull magenta down into the shadows, raise Rose to bloom pink across the upper mids.
Using Berry Nocturne
Where it works
Late-night R&B covers, slow intros and anything lit by club blues, since the blue-keyed violet keeps cool light apart from warm tones. Moodier than Radioactive Rose, and there's no green anywhere in it.
With the music
The grade sits still until you route something. Send B3 bass body to Violet so basslines push blue areas deeper into violet, and put a slow LFO on Rose to swell the pink highs over each phrase.
Starting point
Grape at centre, Violet three-quarters, Rose a quarter, then lift Rose until the brightest areas just turn pink.
