Grainy gradient scenes

Short scenes, about 8 s each, on a soft gradient that drifts slowly under a layer of film grain. Each scene is one of two kinds:

• A title card: a big headline, sometimes with one hand-drawn curve.
• A diagram: a short headline top left, and a simple outline drawing (documents, bubbles, a folder, a grid, a path) that draws in piece by piece.

The look

Gradient. Two or three large, very soft colour fields blend across the frame, with no hard edges and no visible centre. They drift a little over the whole scene (a few percent of the frame, slow and steady, never pulsing). A darker band low in the frame gives the text above it contrast. Use one palette per scene, and keep each palette for its kind of scene across a video. The palettes in the examples, sampled from the clips:
