Clear space

There must always be sufficient space surrounding the Hydro logo to avoid competition with other elements and to maintain its visual impact. The recommended open space is relative to the logo size, and is 1x the height of the brandmark. Try to allow at least this amount of clear space, it will help give the logo clarity.


Sometimes, the recommended amount of clear space will not be possible to achieve. In these situations, strive for a minimum open space of 0.5x the height of the brandmark. However, please note that the legibility and visibility of the logo takes precedence over clear space. Use common sense to find the right balance.

Show special care when the logo is placed next to other logos. The distance should be minimum ‘recommended clear space’, and it should always be clear that the logos represent different companies. Also the Hydro logo should never be used as part of another logo/symbol.

Minimum size

When the brandmark is used by itself, the minimum width is 5 mm. This is not necessarily a recommended size, it is the absolute minimum.

logo, company name

To ensure clean and legible lettering and art detail, the width of the primary Hydro logo must never be less than 10 mm.


These are the official versions of the Hydro logo. No other arrangement or color is allowed. They are available in EPS format, compatible with Adobe Illustrator CS6 or newer for both print (CMYK and Pantone) and screen (RGB).

Although the blue version of the logo is most widely used, it is never wrong to use the aluminium-colored logo. You are free to choose the version that works best for your specific project. The dark blue provides a distinct presence on light backgrounds, while aluminium is more subtle. Aluminium is preferred in premium printed matter where it may be reproduced in metallic Pantone 877 or matte silver foil.

The white (negative) version of the logo is intended for dark backgrounds. If the logo cannot be reproduced in color, use the black, white, or aluminium (CMYK) version. Never convert the dark blue logo to grayscale.
