Bank and financial-service names and marks are owned by their respective owners. These marks identify the selected institution. They carry no employment verification, endorsement, or trademark license from their inclusion here. The project MIT license does not cover these marks. Runtime artwork consists of bounded local PNG images and audited passive SVGs. Sampled colors identify the source palette. Formal brand-standard RGB values require an official manual.

Marks retain their original geometry. Documented preparation may include a source-native crop, proportional raster conversion, whitespace normalization, or extraction of original vector paths. Foreground lockups and decorative pictograms are separate assets. Historical raster provenance remains in provenance.json. The premium catalog records source URLs, SHA-256 hashes and derivation in ../bio-symbols/provenance.json and docs/research/bio-bank-branding.md.

Transparent PNG catalog update
The bank registry now binds PNG artwork by exact SHA-256 and dimensions. Existing transparent PNGs are retained unchanged. Audited vector masters are rasterized on a clear canvas without removing painted elements, at the highest bounded resolution that fits 262144 bytes. The registry references the official source and the published PNG. Older URLs remain for existing clients. MoMo uses the same artwork for web and print, rasterized from the original 72×72 coordinate system with an explicit viewBox.

Payment surfaces use the same full artwork where appropriate. Separately verified positive variants remain where an original Bio design uses a dark-ground lockup. The payment asset manifest lists the served path, source and digest.

Logo selection by format
Authored dark mastheads use the verified reversed lockup recorded in the registry. Shared light formats and print use the corresponding positive lockup. The VietinBank white lockup uses the intact wordmark and emblem from the official Investor Relations footer asset, with the separate slogan outside the exported area: https://investor.vietinbank.vn/documents/d/investor/logo_white_slogan_vi

SaigonBank positive artwork uses the user-provided PNG attributed to SaigonBank, unchanged at 668×372 pixels. The authored dark format retains the reversed artwork from the bank's 2025 annual report. https://vi.wikipedia.org/wiki/Tập_tin:Logo_SaigonBank.png

SHB 2026 uses the six exact paths from the bank-issued color master supplied by the project owner (PDF SHA-256 9b275f2107bb92e5f47a85ee96224d8fe09c0db6218a0a41188f56f5367beddf). Digital fills use the official brand guideline HEX values. The light format uses the positive lockup. https://www.shb.com.vn/mot-ky-luc-vua-xac-lap-tai-dhdcd-ngan-hang-top-5-tmcp-tu-nhan-viet-nam/

BAC A BANK uses the project owner’s supplied Wikiland PNG link. The 930×260 positive lockup trims transparent margins. The 168×167 watermark crops the five-petal emblem and excludes the adjacent wordmark. Both preserve the source colors. The supplied Downloads kit was used for visual comparison. The new PNG is served locally. Earlier public filenames remain available. https://wikiland.vn/wp-content/uploads/ngan-hang/bac-a-bank/logo-bac-a-bank.png
