How to add color to wall?

You can paint vinyl siding if you prime it first. If you use Gripper or Binz 123 water base. Put 2 coats on and let dry over night and them paint whatever will make your boring corner exciting.

Use outdoor command hooks and put up a metal picture,make a container of flowers,put a bright rug in front of the door.

I bought some stainless steel hangers on amazon and hung a wreath. It added color without destroying the siding. They're called siding hooks. Good luck!

Don't let the siding scare you ! 3M makes hooks and those strips that are specifically designed for outdoor use. I used them 2 years ago to hang a string of lights around the edge of my patio and have had zero issues . So find a lovely tin sign or make one out of reclaimed wood and hang it up . Or if you still don't feelcomfortable with the idea , prop something large up against the wall to make it a focal point .

Have you ever tried the outdoor Command Hooks? You could hang up a pretty wreath, or some garland... Do you have enough of an eave over the space to make/ hang a pretty wind chime?

I had a wall like that and put a small potting table there ,it stands taller with shelfs and I put potted plants sitting on it and a few cheap gardening tools to look like I was that good. I used it too but not as much as it called for, lol. Looks real cute.

Great ideas... For some reason this wall just had me baffled!!

At Christmas time you can buy hooks that have suction cups to hold wreaths or whatever. They come in various sizes

How about painting the table a bright color and get some outdoor coordinating pillows for the chairs. Get some potted plants, something tall if possible like a clematis.
