Your idea

A blue ceramic cup for a square product photograph, on a cream background.

A more useful prompt

A blue glazed ceramic cup centered on a cream surface, handle visible, soft window light from the left, gentle contact shadow and crisp glaze detail. Clean square product photograph with a quiet background and consistent blue color.

Your idea

Create a poster with the exact words OPEN STUDIO, using orange #F97316 for the lettering.

A more useful prompt

A minimal poster with the exact words “OPEN STUDIO” centered in large bold lettering, colored orange #F97316. Cream background, balanced spacing and a clear text hierarchy. Keep the requested words unchanged; verify spelling after rendering.

Write what should appear

FLUX.2 uses natural-language descriptions rather than Midjourney flags. Describe the subject, action, style and context. This tool converts exclusions into positive instructions, such as an empty street or sharp focus, instead of adding a negative prompt field.

Exact text and image edits

Enter the exact lettering and name the object each color belongs to. In edit mode, separate changes from preserved details and attach the source image in your FLUX app. Review lettering and brand accuracy in the rendered result; this tool does not inspect references or create images.
