Google’s October 20, 2026 announcement describes retained brand style in Gemini using a website, brand kit, fonts or palettes, paired with Nano Banana 2.1. It announced a global rollout over the following days. Check the controls and generation allowance in your actual account before planning a batch of assets; the dated announcement does not prove every account has every feature today.
Give the style a concrete job
For a fictional stationery shop, provide a permitted reference, two approved color values and the exact product name. Ask for one square launch graphic with space for a caption. Keep unrelated customer information out of the reference package.
Save the guidance through the available product interface, then request a second asset using the same style. Check that the result actually reuses the intended palette rather than merely repeating the instruction in chat.
Inspect what will be published
Open the exported file and compare colors, spelling, lettering and pixel dimensions. Uploaded fonts do not guarantee flawless rendered text, and a retained style does not guarantee identical subjects. Keep editable original lettering where exact typography matters. Approve each final asset independently.
For a reproducible sample, use the fictional palette #123E2A and #F0C94D. Compare a flat color area in both exports, not only an antialiased edge; keep the original palette values beside the files.
