Knowledge looks open. Everything a volunteer needs is free (Montserrat, Source Serif, the palettes, the templates), colour comes in flat blocks anyone can reproduce, and even the image credits are part of the page. Our reading
Which palette colours lead: each affiliate (and each campaign) picks its own 4-6, and the Foundation site rotates them section by section.

Knowledge is human.
Founded in 2003, the Foundation hosts Wikipedia and the other Wikimedia projects and supports the hundreds of thousands of volunteers who edit them. The Wikimedia brandmark shows a vaguely human figure raising its arms in celebration; the Foundation logo, drawn in 2005 by Neolux, shows a figure holding an open book.

The Wikimedia Foundation is the nonprofit that hosts Wikipedia and the other Wikimedia projects. It supports the volunteers who write and check them, the technology that keeps them fast and private, and the legal and policy work that protects everyone's right to free knowledge.

The Foundation logo is the brandmark (a figure holding an open book, drawn in 2005 by Neolux) plus WIKIMEDIA / FOUNDATION in Montserrat, in a horizontal and a vertical version, only in black or white. The wider movement shares the Wikimedia brandmark (a figure raising its arms) and a tricolour Community logo for user groups.

A shared palette keeps a decentralised movement recognisable while letting each affiliate pick 4-6 colours that fit their culture.

Three palettes: Core (black, white and three greys), Legacy (the movement's green, blue and red, each with an AAA version for white text) and Creative (11 strong colours from community groups and the Wikipedia 20 birthday, each with a light tint). The site runs on white and black, with Blue AAA for links and the donation bar, Green AAA for Donate, strong colours for action cards and light tints for highlight chips and band grounds.
Not published: colour proportions or ratios; which colour is the primary for the Foundation itself.

One word in a colour chip · the hero headline (and the guide's own campaign posters)
Do Flat Legacy and Creative strong colours as whole surfaces, each carrying white Montserrat Bold (on Green AAA #246342, Red #990000, Blue AAA #0C57A8, Purple #5748B5, Blue #0063BF) or black text (on Yellow #F0BC00). Radius 4px or full-bleed; no gradients, no shadows. Each block one colour; neighbours never repeat a colour.
Saturated movement-colour blocks · action cards, donation bar, subscribe band, volunteer panel
Do Every image carries its title, author and licence (TASL), linked to the source; Commons files get the Commons icon. On a landing page: a full-width off-white (#F9F9F0) band of small thumbnails with credits in three columns.
Credit every image · a Photo credits block before the footer, and captions
Do Continuous, fluid, uniform pen-like black stroke, not too thick, with one flat palette colour or a circular shape behind; light ink/pencil texture at most; used large and in one colour.
Hand-drawn line illustration with one colour · stats, spot illustrations
Do Core palette carries the frame: black logo and type on white, white reverse logo on Black 75 #404040; colour enters in blocks, chips and photos, never in the logo.
Black, white and the logo in black · nav, headings, logo
Specimens use sample copy, not Wikimedia’s.
The content is the brand; graphics stay simple enough for any volunteer to reproduce.
No ornament system: the recognisable pieces are flat colour blocks, the coloured highlight chip on one word, hand-drawn line illustrations, the puzzle-piece globe from Wikipedia, and attribution credits. The guide also borrows Wikipedia's diff interface as a storytelling device.

Neutral, universal symbols that work across cultures and right-to-left scripts.
Codex icons: monochrome, geometric, front-facing outlines on a 20 dp canvas with a 2 dp stroke, sharp corners, freely licensed.

Feels made by people, which is the point of the movement.

Line illustrations from the Wikipedia 20 campaign by Karabo Poppy Moletsane and Jasmina El Bouamraoui: continuous, uniform pen-like strokes, hand-made feel, often one colour or a circle of colour behind.
An insider's family album builds trust and shows the community behind the content.


Real moments at events: people engaged with each other and with Wikipedia, not looking at the camera; natural light, bright saturated colour, imperfect framing allowed.
