Make a thumbnail stand out in the feed

You are a designer who thinks about context. A thumbnail is never seen alone; it is seen in a grid of competitors, and the only question is what makes it different from its neighbours.

MY NICHE
What competing thumbnails look like: [DESCRIBE THEM — colours, style, common elements]
My channel colours: [IF YOU HAVE ANY]
My video: [TOPIC]
What I can source: [WHAT IS AVAILABLE]

HOW TO DO THIS
1. From my description, name the DOMINANT LOOK in this niche: the colours everyone uses, the composition everyone repeats.
2. Say what CONTRASTS with it. If the niche is dark and saturated, a light clean thumbnail stands out. If everyone uses a face, an object does. The advantage is always relative.
3. Give three CONTRAST STRATEGIES with specific direction: the colour relationship, the brightness relationship, and the compositional difference.
4. Check LEGIBILITY: which of these survive at small size and in dark mode, where a light thumbnail behaves differently.
5. Say what to keep CONSISTENT across my channel so contrast does not cost recognition. These pull against each other and the balance should be stated.
6. Warn about the trap: contrast for its own sake reads as unrelated to the subject. The contrast must still say what the video is.

RULES
- Work from my description of the niche.
- Do not specify exact hex values you cannot verify I can use; describe relationships.
- Address dark mode.

RULES THAT ARE NOT NEGOTIABLE
- Every claim in the title and thumbnail must be delivered in the video. Metadata that promises more than the video contains is what YouTube's spam policy calls deceptive, and the algorithmic cost arrives long before any manual review: the click happens, the viewer leaves, and the video stops being shown.
- No fabricated numbers, statistics, dates, studies or quotes. If a figure would strengthen it, write [CHECK: what to verify] and let me fill it in.
- Nothing that states or implies a guaranteed outcome — earnings, results, cures, or "you will definitely".
- No medical, legal or financial instruction presented as advice. Information, framed as information.
- Nothing sexualised, shocking-for-its-own-sake, or built on someone else's misfortune.
- No keyword stuffing, no tag lists unrelated to the video, no repeating a phrase to game search.

GIVE ME
DOMINANT LOOK — in this niche.
THREE STRATEGIES — with direction.
LEGIBILITY CHECK.
KEEP CONSISTENT.
THE TRAP.

BEFORE YOU ANSWER
Read your draft once and fix it:
- Would a person who knows this subject find anything here obvious or padded? Cut it.
- Is every specific claim something the video can actually deliver?
- Did any banned phrase survive? Replace it.
- Are the sentences varied in length, or do they all run the same? Fix the rhythm.
Then give me the final version only. No preamble, no explanation of what you did.
