Buildings - colours

Colour plays an important role in how we see our environment and has a significant impact on our well-being. Tastes naturally differ from one person to another but the colour ranges available for offices and corridors are all in calming, harmonious tones to ensure that a change of office does not automatically mean having to call in the painters to redecorate.

The colours presented in the guidelines are as close as possible to the actual paint colours but variations in screen display or print mean an inevitable discrepancy with what they will actually look like on your wall.

Cladding of industrial buildings

As the industrial buildings on the site have a significant visual impact it is desirable to standardise the colour of the paintwork in order to create a uniform whole. Monochrome grey, which works well with the existing buildings, is a relatively neutral colour that does not tend to fade too much as a result of exposure to the sun. The cladding of the industrial buildings on the site must be painted in White aluminium 9006. The finishings (window frames, doors) must be painted in Grey aluminium 9007 alone or in combination with the Black grey in order to create a deeper contrast.

Steel Structures 

To help achieve a consistent look of all elements on CERN site, we propose to use the same colours of steel structors both in surface and underground.
You can find here also the RAL colour of overhead cranes (or other moving objects), since yellow traditionally signals caution. 

In some projects, only one colour has beed chosen for underground as well as for a surface: RAL 5015 - HiLumi.

In other situations we can notice different RAL and it should be then continue with the same colour if modification is needed: 
RAL 6020 Chrome Green - CMS
RAL 5017 Traffic bleu - Building 311
