The MSN Logo for Online Use

Basic Elements of the MSN Logo – Overview

The visual identity developed for MSN helps position the brand as the easiest way to take advantage of the full power of the Web. The MSN logo consists of:

LOGO

The MSN butterfly – a dynamic, colorful embodiment of the effortless, lively qualities associated with the MSN brand. For online use, a version of the MSN butterfly has been created using flat, RGB colors (with no drop shadow). For printed applications, the MSN butterfly is rendered with subtle shading and a drop shadow.

The MSN letters – a distinctive, proprietary arrangement of specially-drawn lowercase letters.

The trademark symbols – legal requirements which must appear in the positions shown on all applications of the logo.

Configurations


The butterfly, letters, and trademarks are arranged in two approved configurations – horizontal and vertical – which have been accommodate most space requirements. Use the preferred, horizontal version of the logo whenever possible.

Important note: The relationships between the elements of the MSN logo are fixed, and must not be altered in any way. Always use the authorized electronic artwork provided.

Clear Space Requirements

The MSN logo is most effective when surrounded by as much open space as possible. A minimum area of unobstructed clear space must surround the logo (both the horizontal and vertical versions) in all situations.

For online applications, this clear space must be at least 0.25x (“x’ equals the height of the MSN letters), as shown here.

CONFIDENTIAL TREATMENT REQUESTED


Please note that, while these diagrams illustrate the positive, full-color treatment of the logo, the same rules apply for reverse reproduction.

CONFIDENTIAL TREATMENT REQUESTED

Color

The logo should always appear in full-color when used online. For online applications with white or light-colored backgrounds, use the full-color (not reverse) version of the logo.

Reverse Applications

For online applications with black or dark-colored backgrounds, use the full-color reverse version of the logo.


Black is the preferred background color for reverse versions of the logo. Other acceptable background colors include dark blue and other dark colors that provide sufficient contrast, but do not clash visually with the MSN butterfly.

Color Palette Specifications – RGB

The colors shown here play an important part in the MSN visual identity, as a component of the MSN logo, and as accent colors on specific applications. Consistent use of these colors will help in building a distinctive MSN brand personality.

For online applications, use these web-safe RGB specifications.

LOGO

Minimum Sizes

To ensure high quality reproduction, do not reproduce the MSN logo in sizes smaller than those indicated here.

CONFIDENTIAL TREATMENT REQUESTED

Do not reproduce the horizontal version in sizes narrower than 47 pixels (0.65 inch).

Do not reproduce the vertical version in sizes narrower than 21 pixels (0.3 inch).

Use of the Trademarks with the MSN Logo

The MSN name, and therefore the logotype has changed from a TM to a ^®. This change is being phased into all logo applications. The trademark symbols must appear on all applications of the logo – ^® next to the MSN letters, and TM next to the butterfly.

The trademarks are set in Microsoft Franklin Gothic Heavy, and print in black or blue (or on one-color versions, in that color). The point size of the trademark is based on the width of the logo, as, follows:

Horizontal logo

2.5” and wider: 5 point

2” up to 2.5”: 4 point

below 2”: 3 point
Vertical logo

1.5” and wider: 5 point

below 1.5”: 3 point
Positions the trademarks according to the diagrams to the right.

CONFIDENTIAL TREATMENT REQUESTED

Misuses – General

These examples illustrate incorrect use of the MSN logo for online use. While each example depicts only one version of the logo (horizontal or vertical), the principles apply to both.

Always use the authorized electronic artwork provided.
