Your house trim is grey tones I think, so there is TREX colour that would complement that, perhaps 'gravel path' and if you want to match your siding, perhaps 'rope swing' but if you prefer the wood look on your deck I would choose a more wood tone decking material and your fence is wood tone as well, perhaps 'tree house'. Most stores have samples that you can take home and see what you like as you consider matching trim, siding or fencing.

Thank you, Elaine! The trim is black and house a beige color. I will definitely check out samples and very wise suggestion regarding matching some of the surrounding colors. I appreciate it, sincerely!

You are welcome, lovely home and outdoor space, enjoy:)
