I have a 10" dob and up to date have yet to see any colour. With the moon so bright, I doubt that I will succeed anytime soon. If at first you don't succeed,.. try, try again right?

Good luck and I wish you clear skies!

there's a nice picture in philip's solar system observer's guide 2005 by peter grego on page 149 it details uranus & 3 of its moons (i think) using a 6" refractor at x188. the picture is about 63mm or 2 1/5" square and uranus 4mm or 1/8" wide and is green. now this is a picture so it will show colour but as you mentioned lack of colour I was wondering whether the dob vs refractor is any thing to consider??? ie no-colour with mirrors vs colour with refractors??? i don't have exp.with mirrors so don't know much about them...but i would guess that it is a very faint kind of green and maybe just looks white maybe??? try some filters, ask around for advice about the diff's between Mirros vs Refractor and get back to me please...i was thinking of uping my 4" refractor to a 6" after seeing that picture i mentioned...also planning to make my own 8" dob/newt at my astro club...
