The visual identity of the HERMES project asserts itself via several aspects of a unified graphic design. Among these are: typeface (headline and body), logos, icons, and colours. As the HERMES suite subscribes to the Open Source philosophy, the design guidelines have had to be kept simple for contributors, but recognisable for users.
The colours of the HERMES project are exactly the sixteen (16) colours of the Solarized palette by Ethan Schoonover:
The Solarized palette is to be used at every opportunity; without prejudice to the generality of the foregoing, this includes:
There is one additional colour. Designated HERMES Blue in English, the HTML colour #81d8d0 unambiguously represents HERMES as a non-profit body corporate; as such, its use is limited to logotypes and icons, HERMES "stash" (promotional goods), top and side navigation bars on this Web site, and advertising. It is to be used sparingly; in combination with the "HERMES" wordmark and a HERMES application icon, it forms part of our intellectual property.
Headlines and textual accents are to be set in Draughtsman A, a typeface chosen for its simplicity and precision (attributes stemming from its inspiration, namely the labelling on architectural and engineering blueprints). It is also distinctive; it was created by Nicholas Edward Werner-Matavka, a member of the HERMES team, and has not been distributed on the Internet until recently. Draughtsman A has an italic variant, but no bold. For this reason, although it may be used for body text, it is not exceedingly suited to this application.
Body text is preferentially to be set in Boing, which was chosen for continuity reasons, as it is the corporate typeface used by QUALCOMM, the erstwhile developers of Eudora. Furthermore, it is a complete typeface, as it has thin, light, medium, semibold, and bold fonts, each with an italic variant. This makes it especially suitable for the foregoing usage.
Finally, a selection of typefaces has been included in HERMES Mail for the pleasure of its users; these do not form a part of the HERMES corporate identity and shall not be further discussed.
The complete logotype of a HERMES product consists of three design elements (HERMES wordmark, wings, and logo proper) and is produced in three proportions (1:1, 1.6:1, and phi). For ease of modification, the authoritative form of a logotype is the Scalable Vector Graphic (SVG) format. Each proportion has a different use, as follows:
At no time is any logotype or wordmark to be rendered in a lossy format such as JPEG. This causes artifacts!
The HERMES wordmark represents us as a collective entity. It may be used in isolation for just that. Otherwise, it shall form part of each product logotype, such that it has equal prominence to the pictorial portion of the foregoing. It is composed of the letters H-E-R-M-E-S, hand-drawn (and therefore not part of any particular typeface) in vertically biconvex fashion (and by definition subtending on both sides an arc of a circle).
The central "hub" of the logo represents the individual product: a globe for HERMES Mail, a global network for HERMES WireShare, a globe surmounted by the letter 'X' for HERMES Mail/X.
