Outline logo

The outline version of the CERN logo has a greater colour flexibility: where the background is not white the outline version of the logo must be reproduced in black, white or a greyscale value which gives a high contrast and good readability. In some special cases you may be authorised to reproduce the outline version of the logo in an other colour.


Accurate reproduction of the CERN blue is essential.
