Are there any long-lasting (10 years) alternatives to Dulux Weathershield for my front door? I don't want white, black or grey paint and I've tried testers of all the other colours and I just don't know what they're thinking! They are all hideous and garish. I just want a classy dark green or dark blue (or similar) and theirs are so bright. They definitely had a better range last time I did this.
