Parts of Colmar are OK, basically the old part. Parts are a semi-industrial mess.
Better in my opinion to look at the quite attractive smaller towns and larger villages instead. Google up the Wine Route, here's a start: http://www.ribeauville-riquewihr.com/en/discover/alsace-wine-route.htm and look at what the towns in and around it might offer.
One tiny word of caution. If you go too far out of the main tourists season some places all but close up for their own holidays, before they kick-off again for Christmas and the New Year.
As ever, streetview gives you some pretty good clues.
