Just personal opinion I guess but the green and black stripped kit by Errea a few years back looked good as the badge and logo all fitted the same colour scheme. Look at the baby pink kit Man Utd had this season, sticking the red 'home' badge on that would have looked utter shithouse.
Unfortunately we do not blend our badge to match the away kit colours. We just stick a Blue badge on whatever identikit we get which is a real shame as kits look so much better when the badge is bespoke to match the shirt (see Man Utd and Real Madrid for teams that do this really well).
