What it is

## What it is A color grade that pushes a clip into a cold, dread, low-light register: blacks lifted+crushed via a `curves` shadow tweak, saturation pulled to ~0.78, a faint green channel shift, and contrast slightly under 1.0. This is the `analog-horror` preset in the production color-grade table (validated against the analog-horror-fridge postmortem). ## When to use it - Horror / liminal / dread registers (silenthill, backrooms branches). - Any clip that came out of the image model too bright/clean for the mood. ## Knobs This is a fixed preset — the three sub-filters (`eq`, `colorchannelmixer`, `curves`) carry the tuned values. For a warmer or punchier look, swap the preset name (`tv-commercial-soft` / `tv-commercial-strong` / `cinematic-teal-orange`) in the same color-grade helper.
