Logo

The logo as a system

The Interzo logo is a system of two formats, chosen by the space available:

• Lockup: the mark and the wordmark “interzo” side by side. It is the primary expression of the brand and the default in any application with comfortable horizontal space.
• Mark: the house on its own. It covers square and small formats where the full lockup cannot breathe: app icons, favicons, avatars, stamps.

Both formats come in the same four color treatments: primary (espresso on light backgrounds), reversed (paper on espresso), on garnet (paper on garnet) and monochrome black. The logo is always a single color, and its shapes never change between treatments: only the fill does.

The wordmark never appears without the mark. The mark can stand alone; the wordmark cannot.

The lockup

The lockup is the signature of the brand. It leads on the website header, documents, email signatures, partner materials and every editorial application where it has room to sit on one line.

Espresso is the color of the logo. The reversed and garnet treatments are the same logo in paper, placed on the two brand surfaces dark enough to carry it. Garnet is a background for the logo, never a color for it.

The monochrome black treatment is a functional fallback, not an aesthetic alternative. It exists for the contexts where espresso cannot travel: single-ink printing, engraving and embossing, faxed or legal documents, black-and-white press, and co-branding sheets that admit one neutral mark only. Reach for it when the medium forbids color, never by preference.

The mark

The mark is the house on its own. It works where the lockup would be too wide or too small to read, and where the name is already present nearby: the app icon on a home screen, the browser tab, a social profile, a stamp on a printed card, a watermark on a document.

The reversed and garnet packages also include the mark set on a square block of its background color, with the clear space already built in. Use those files as they are for app icons and profile pictures: platforms crop square avatars to a circle, and the built-in clear space keeps the house whole inside it.

Construction and rationale

The mark is a house drawn as a single heavy outline: a pitched roof, straight walls, a flat base and softly rounded corners, symmetrical on its vertical axis. Inside it, a stem rises from the floor and stops just below a circle. Stem and circle form a lowercase i: a figure standing inside the house. The stem divides the interior into two equal openings on either side.

The wordmark is set in lowercase with the same heavy, even stroke, flat terminals and round bowls. Its letters are joined where they meet: the i curves into the n, the foot of the t runs into the e, and the base of the z runs into the o. The name reads as one continuous gesture rather than seven separate letters.

One i, twice

The i inside the house is the i of the wordmark. Both stems end in the same cupped top, and the circle in the mark has exactly the same diameter as the dot of the i. The walls of the house, the stem inside it and the strokes of the letters all share one weight.

That repetition is what holds the lockup together. The mark is not an illustration placed next to a name: it is the first letter of the name, given a roof. It is also why the mark can stand on its own: even without the wordmark, the house still carries a piece of it.

How the name is written

In running text the brand is written Interzo: initial capital, lowercase after, like any proper noun. It is not set in all caps or small caps.

The lowercase of the wordmark is a graphic decision, not a spelling. The logo is an image; the name inside a sentence is a word, and as a word it follows the rules of the language.

Clear space

Every version of the logo keeps a minimum clear space free of text, images, edges and other graphic elements. Nothing enters that perimeter.

The unit of measurement is x = the diameter of the circle inside the mark. Minimum clearance is 2x on every side, for the lockup and for the mark alone.

The unit is taken from the circle because the circle is present in every version of the logo, so the rule scales with it at any size and never needs a ruler. At 2x the protected band is a little over a third of the logo’s height: enough air for the house to read as an object and not as part of the layout around it.

Minimum sizes

Below a certain size the circle inside the house closes up against the stem, and the mark stops reading as a figure inside a home. The minimum sizes keep that gap open and the circle round. Size is always measured by the height of the logo.

When the lockup would fall below 24 px or 8 mm, switch to the mark rather than shrinking the lockup further. For general use, give the lockup at least 32 px or 12 mm of height.

The browser favicon is the one accepted exception to these rules. In a 16 px tab slot the reversed mark sits on an espresso tile with its clear space reduced to 0.75x, so the house renders as large as the slot allows. Every other icon size, from 32 px up, follows the rules above.

Color treatments

The background decides the treatment. Use the table to pair them; any background not listed needs the contrast of one of these pairs before the logo goes on it.

On photography, place the logo over a calm, even area of the image: espresso where the area is light, paper where it is dark. Never place it across faces, busy detail or a boundary between light and dark.

The logo is always one color. The mark and the wordmark never take different colors, and no part of the logo is highlighted in garnet or any other accent.

Misuse

The logo is a fixed element of the system. It is not stretched, recolored, rotated, rearranged or given effects, and its parts are not used separately except for the mark on its own.
