Hi Pete
Unfortunately with deep space objects colour is all but non existent, they are simply too faint even with a very big scope to activate the colour cells in your eye. The very brightest nebula (M42) I once believe I could catch a tinge of pink with my 12" on a night of exceptional clarity, but certainly nothing like the photos you see.
Stars certainly have discernable colours and many multiple star systems have contrasting colours (Albireo in Cygnus or Beta Cygni is a prime example currently visible) which are very pretty and make fine targets.
I use a GSO 12" which is identical to the Bintel one mentioned. It is a fine instrument for the money, but there are a couple of caveats. It would be difficult to transport if I had only a small sedan and it can be a little cumbersome to move around the backyard. If those 2 things are issues, a collapsible or truss dob is often a better way to go.
