Approved Logo Assets

Use the files in docs/source/images/logos/ as the canonical project logos for README files, documentation pages, presentations, and community material. Use the logo(s) as supplied whenever possible.

Colours

The approved logo palette is intentionally restrained:

Role

Colour

Hex

Primary logo gold

muted warm gold

#B4A069

Light background

warm off-white

#F7F4EF

Neutral text

charcoal

#262626

Reverse background

white

#FFFFFF

For project material, prefer the primary gold for logo strokes, accents, and small highlights. Use neutral text colours for readability. Avoid recolouring the logo into unrelated palettes unless a single-colour accessibility or production constraint requires it.

Minimum Size

Keep the logo large enough for the wordmark and arrows to remain legible:

  • Digital use: at least 120 px wide for the full logo.

  • Small icon or favicon use: at least 32 px wide.

  • Print use: at least 25 mm wide.

If the wordmark becomes hard to read, use a larger size or switch to a simpler project mention in text.

Clear Space

Leave clear space around the logo equal to at least one eighth of the logo diameter on all sides. Do not place text, badges, partner logos, or dense graphics inside this area. More space is preferred on title slides, posters, and documentation headers.

Acceptable Modifications

You may:

  • Scale the logo proportionally.

  • Place the logo on white, warm off-white, or another calm high-contrast background.

  • Export the logo to another raster format when required by a publishing system.

  • Use a single-colour version in primary gold, black, or white when technical constraints require it.

Please avoid:

  • Stretching, squashing, rotating, cropping, or redrawing the logo.

  • Changing the relationship between the arrows, circular mark, and wordmark.

  • Adding shadows, outlines, gradients, filters, or decorative effects.

  • Placing the logo on busy backgrounds where the wordmark is difficult to read.

  • Using the logo in a way that implies endorsement of an external project without permission from the refineGEMs maintainers.
