I'd be worried that red brick , presumably white door jambs , then a walnut or mahogony ( dark walnut ) look door will look cliched 70's .

A cedar or even something like Jarrah will be different enough to the brick ( again , making the assumption you have crisp white or similar to break the tones ) to look the part IMO . Of course , the actual design of the door will have a slight bearing , but personally I can't think of too many options where I would prefer a walnut or mahogony tone , unless you were really embracing the era and have yellow dimpled glass inserts too haha .

Not particularly helpful.

It would be helpful if there was a photo of the brick.

Hi sorry maybe my post wasn’t very clear. Happy with the walnut colour finish I am hoping to achieve. Interested in peoples experience of staining Canadian Ash and the products they used. Stain can throw a different colour depending on the wood and I haven’t used Canadian Ash before. Trying to avoid that reddish Jarrah look.

Thank you
