Hello and welcome. Sorry for the mix up!
When I try to duplicate your technique, all I get is an amalgamation of the two colors I have on my color layer. I don't think this is how match color should work.

It "kind of" did it with only one color on my color layer. It's still not right!

This is not how I would go about this process.
I would place a Solid Color Adjustment layer above my wall selection layer, set it to "Multiply", then clip it to the wall selection layer.

If you want to change the color to something specific, double click the Solid Color Adjustment layer, another color picker will open, enter the hex code of the color you want and click OK on your color picker. 5 to 15 seconds to change colors. Always editable!

If you really want to be organized, you could also move this process to a smart object.
