White, blue, black, grey, but not restricted to those colors.
Our Ideas and Additional Information:
The logo will be used in Switzerland where we usually prefer bright, minimalistic and abstract logos, we would like to avoid the use of the usual houses and roof gimmicks. Typographic modifications are welcome. For the rest, we are confident in the creativity of the designers here and don't want to set strict guidelines or exemples. Thanks in advance for your participation. Laurent
