I tend to stick with the general color scheme of the game. Green rooms were programmers, blue was Designers, and red was Artists. Purple I made for leaders, because it's the color of royalty. Unfortunately the room lables and color styles don't get saved along with the floor plans in the workshop when you download it. But, I did think about that too.

Each room has bit of open space to it, that allows you to click that open space, and select the room options from the right click menu. Then you can make your own style. That's the important thing. I didn't intend those room colors to be set in stone.

If you need three blue rooms, and you want blue to be for just to build a piece of software, then you go ahead and do that. The colors aren't the imporant part of this layout. What matters is the traffic flow of employees getting up repeatedly during the work day to get coffee, meetings, bathrooms, vending, food, and then leave for the day.
