Floor Plans at different levels show in slightly different colour shade

[robinhill833400]

I have a problem in that walls on a first floor plan show differently to walls on a ground floor plan, and I want them to look the same.
Colours at first floor become darker and greyer.
They are the same construction using the same elements.
I have tried drawing a wall on ground floor and raising it to first floor where it shows darker, so I think there must be some difference in the properties of the floor plan, but cant detect any.
Phase and Phase filter are the same (Existing and Show All).
The colour difference still shows when placing the views on a sheet and printing it out, so its not a graphics card issue.

Anyone got any ideas what settings and where they are, that might be causing this?

Thanks

Have you tried creating a view template from the 'correct' plan and applying it to the incorrect plan? Do the graphics change and match? If so then there is probably a difference in the settings. Ambient shadows, consistent colors, filters, underlay, view range... all might affect graphics.

I was going to say 'underlay' too. Perhaps even 'visual style' (box at bottom of screen)?

Thanks, creating and using a view template was a good practical solution that worked. Still puzzled by what setting got changed though. Checked the above suggestions and couldn't find it, but it must have been something fairly deep in the settings as all the main ones appeared the same.
Many thanks for your Practical solution!
