Not a fan of the colours although they would look even worse in a smaller darker kitchen.
If you go with Wren DO NOT USE THEIR INSTALLERS
Unless you like paying over the odds for a shit install. Don't believe the salesman's lies about using their installers making life easier. How if there is an issue, the installers can get things sorted overnight rather than you having to wait until their next delivery in your area. Total lying bollocks.
I have a Wren kitchen which I'm very happy with. Just wish I'd stuck with installing it myself. Very competent DIY-er but was looking for a stress free installation. Boy, did I get that wrong!!
