True Crime thumbnail style

Moody high-contrast portrait with a blood-red accent — true crime / mystery look.

What this style looks like

When you pick the True Crime style in Thumby, the AI agent assembles every render around these visual rules — the same prompt scaffolding our system uses to build a CTR-tuned thumbnail in roughly 60 seconds:

moody high-contrast portrait of a single subject half in shadow, optional faded newspaper-clipping or case-file collage texture in the background, gritty photographic feel

Color, lighting, and mood

near-monochrome cool palette of charcoal, deep teal and bone white with a single blood-red accent — a thin streak, lipstick, or stained word — heavy film grain, soft vignette, low-key lighting

Composition rules

On top of the look itself, every render in this style follows these layout principles — tuned to keep the thumbnail readable at mobile-feed size and to maximise CTR on YouTube’s 2026 algorithm:

subject's eyes locked on camera or sharply off-frame, face cropped tight on one side and dropping into deep black negative space on the other for a stark three-word headline

Who this style is for

Pick the True Crimestyle when your video lives in the niche this look was tuned for. Most users pair it with a one-line topic — the AI agent writes the full prompt, applies the style on top, and ships a 16:9 thumbnail you can download or upscale to 2K / 4K straight away. If you’ve got a face or product photo to anchor the render, drop it in as a reference and the style renders your subject in the look above instead of a generic stock figure.
