Prompt
A vintage travel poster of a lunar colony — clustered geodesic domes glowing on the grey moon surface, an astronaut in a bulky retro spacesuit planting a flag in the foreground, a large crescent Earth in the star-flecked black sky, mid-century WPA travel-poster style, flat bold color blocks, a limited teal, cream and burnt-orange palette, screen-print grain, an empty banner band across the top reserved for a title, no lettering

How to use this prompt
The retro-travel-poster look lives or dies on the flat, screen-printed finish — say 'flat color blocks, limited palette, screen-print grain' or Flux drifts into a photoreal render and the vintage charm vanishes. Keep the palette to two or three flat tones (teal, cream, burnt orange) so it reads as a mid-century print rather than a photo. Earth works best sized large and graphic in the sky, not a tiny accurate globe. The blank banner is the trap: Flux almost always fills reserved title bands with garbled faux-lettering, so keep the band empty, expect to inpaint, and set your real headline in a design tool afterward.
Variations to try
- Mars outpost version — swap the lunar domes for red-rock Martian terrain and a dusty pink sky, keeping the flat WPA travel-poster style
- Night-launch scene — replace the flag-planting astronaut with a rocket lifting off from the domes against a star-filled sky
