Prompt
A high-energy YouTube thumbnail background: an exploding desktop computer with dramatic orange sparks flying against a deep teal gradient background, motion blur on debris, bold white 3D headline text reading "I BROKE IT" with a black outline on the left side, hyper-saturated colors, sharp studio lighting on the subject.

How to use this prompt
Flux is the only model in our library we trust with in-image headline text — keep it to three short words in quotes, all caps, and describe the treatment ("bold white 3D with black outline") or you'll get thin default lettering. The orange-on-teal complementary pair is the highest-contrast combo at thumbnail size. If the text renders misspelled, regenerate: it's seed luck, and fixing it beats compositing.
Variations to try
- Money niche — "a rising golden bar chart with coins scattering, text reading 'IT WORKED'"
- Calm tech review — "a laptop on a clean desk with soft neon backlight, text reading 'WORTH IT?'"
