How to use this prompt
"At a slight tilt" is quietly critical — a perfectly upright question mark looks like a font glyph, while the tilt makes it read as a 3D object with real weight. The diagonal blue-and-yellow split delivers maximum contrast at feed size, and DALL·E follows named-color splits far more reliably than a vague "colorful background". Keeping the mark in "the right two thirds" leaves your question text zone clear on the left; check that the dot of the question mark hasn't drifted into it before you export. If the gloss looks dull, ask for "stronger studio highlights on the curve" in a follow-up message instead of regenerating from scratch.
Variations to try
- Exclamation version — swap the subject for "a giant glossy red 3D exclamation mark" over "a black and warning-yellow diagonal split" for shock-fact videos
- Trio version — "three floating glossy 3D question marks in descending sizes, staggered in depth" for multi-question quiz formats
