SeaGL Style Guide

The goal of this guide is to group the common effort on the creation of design materials for the Seattle GNU/Linux Conference. It describes best practices for creating new materials and applying the visual identity of the event.


This section contains information about the visual elements of the conference, how to use them and best practices. All design assets are licensed under CC BY-SA, unless otherwise specified.

Our logo is the most recognizable SeaGL symbol. Is composed of two elements: The low-poly seagull illustration with a circular two blue tone background and a gray ribbon underneath with the conference name.

As the logo is multicolored, we have limited background color options. White and the blue variations described on the color palette are the options for multiple context usage. Also, a special blue-white background with gold separation on the ribbon is used.

A minimum clear space around the logo is required, about 50% of the diameter on each side. Using with small size are not recommended, due to the logo complexity.

For the online events, there is a special version where the seagull is with a microphone. It follows the same restrictions as the classic version.

The logo images may be used without advance permission, subject to the following requirements:

  • The use is only in connection with promoting the SeaGL conference.
  • The use does not imply sponsorship or endorsement by the SeaGL conference.
  • Where possible, the logo hyperlinks to or an appropriate page on that site.
  • The logo images are not altered, except to proportionally resize.

Font Styles

The SeaGL typography is one of the core elements that defines the conference design style. We use two fonts, Dosis and Lato, according to the following:

  • Dosis (Regular): Applied on headers / titles; capitals only.
  • Lato: Other text elements, like text body.

Text alignment can vary by application, the important thing is to stay good in context.

Color Usage

The color usage must respect others elements rules, like the logo. Mainly, the blue and white variations are used for backgrounds.

The White 2 color is used in digital material with focus on text, such as the website, for better reading.

Gold is applied to action links and to contrast with the blue / background, depending on the situation.
