I would be incline to paint it in the green taken from the colour of the leadlight this will make a feature of your front door but at the same time won't detract from the leadlight or as others have suggested a brick red to complement the brickwork.

Thanks for you opinion, Judy! I will ask colour selection consultant whether I can get the same colour of WIP door as joinery doors once I hear from the builder. It has been hard to reach them lately lol

haha believe it or not, my garage door is still covered up in alucobond cover, so i haven't actually seen the colour yet and i don't want to peel it off just yet incase it gets damaged...Will wait til all the tradies have finished. Here is a photo of a section of my garden jocelyn lawry designs & colour - Not bland anymore??? :))

Natural White & Whisper White will both work well with Polytec Classic White. I would steer clear of Lexicon - it's a little too cool to work well with Classic White. You might find it easier if you get some sample pots & paint up some large boards as both Whisper White & Natural White will look lighter and 'more white' once they are on the wall. Lexicon half or quarter would be incredibly light as a wall colour and too stark for most applications.
