The Bayer Cross and logotype

Use this version to add impact where it appears to improve readability and recognition and in restricted spaces or at a small size (e.g. sponsor walls at events or advertising at sports events).

Minimum clear space

Always allow a space of at least ¼ of the logo diameter all around the square on which the logo sits.

If only a single version of the Bayer Cross can be used (e.g. in social media apps) and the background color may change (e.g. between smartphone light and dark mode), the Bayer Cross must be displayed inside a white circle.

Photographic backgrounds

On light and dark photographic backgrounds, use the full-color positive and reverse Bayer Cross versions respectively, as shown. If standout is compromised (e.g. on green or pale blue backgrounds), use the white version.

The full-color positive version works on backgrounds with a tonal range equivalent to 0–20% tint of black. The full-color reverse version works on backgrounds with a tonal range equivalent to 60–100% tint of black.
