OK. I am currently using Google sketchup to produce a classroom plan of our main building which is all nice and finished but I am haivng a little colouring in problem. (And I hope this is going to make sense)

I've got the building plan at a slight angle on screen so it looks more visually appealing and colour coded the department. When I produce the key, a seperate drawing, I've drawn a square and coloured it in for each department. The key however is a top down drawing and the colours are slightly differnet to the building plan. When I view the building plan top down the colours change slightly.

I'm guessing that there is some kind of lighting effect going on and sketchup changes the colour of things as you rotate the model. Is there a way to turn this off? I want an object to be the colour I pick and not change slightly depending on which angle I view it from. I can't seem to find a way to do it and it's causing me a problem.
