Great topic @Lindbert Guerra!

When we painted our shop we went with a two-tone. The roof and top half of the walls were painted white, while the bottom half of the walls were painted gray.

This was done for very practical reasons. Our craft is one that requires a lot of light. By painting the roof and top half of the walls white, we're able to keep the shop brighter.

The bottom half of the walls were painted gray because they're likely to get dirtier faster -- with exhaust smoke, dirt and other gunk. The gray masks that unsightly dirt and gives us longer time between paint jobs.

@Nadeem Muaddi good thinking! I didn’t even think about how the colors would effect light output in a shop.

Thanks Nadeem very helpful ideas..very much appreciated..

When I took over my company I also thought about the colour design for a long time. Because Nadeem is absolutely right that one counteracts the dirt with grey or dark colours. However, I was totally fed up with the dark colours. (For 12 years the lower parts of the walls were navy blue. And because the lighting was also very bad the whole workshop was a dark hole. Therefore, after the renaming of the company and the logo development, I have to follow the logo colors in the workshop and give the corporate identity even more profile. I admit that I exaggerated a bit with the base with the seam pattern. However, one should not underestimate what it does to the customer's subconscious. And I have often received the feedback: "you immediately notice that creative people work here" - without the customers having ever seen my work before.
And since I have taken over the company in all points in bad shape, I know how much the optical design of the workshop also contributes to the success of the company. Of course a bucket of paint doesn't turn you into a successful company, but the bucket can help. Here are a few pictures that illustrate what the bucket does for a difference.

@Jens Jesberg wow! What a difference before and after. The before reminds me a lot of the rail station I worked at for the Deustche Bahn in Nuremberg. Blue everywhere, no matter how clean they kept it, looked old and dirty.
