Im trying to match the paint color of a wall that was half painted. I use the eyedropper on the color i want and begin painting with the color replacement tool. The color is not even close. Its way too bright. The same happens when i paint with a regular brush on a layer set to color blending mode.

Hi
A couple of things to look at :
1.If you are using multiple layers (including adjustment layers) your eyedropper tool may be selecting the wrong layer. Select the eyedropper tool and go to the options bar. Under Sample there is a drop down box to select from
If using multiple layers (think composite) with adjustment layers above it - Use "Current and below"
2. Colour replacement usually works in Colour mode. In that mode it paints the Hue and Saturation of the brush color but leaves the luminosity of the color it is replacing intact. The viewed colour can therefor look lighter or darker depending on that previous luminosity

Thanks, but that has nothing to do with it. The swatch color is correct. When i paint, its nowhere near the swatch color.
As you can see, the swatch color matches what i sampled. That's not the problem. When i paint, the luminosity or something is not matching. The color i painted, as you see is beige, not the olive brown that i sampled.
Switch to Lab Color confirms that the only significant shift is in Luminosity.
The elephant in the room is the out of focus image and abbreviated tonal range. While the range is easy to adjust, creating a suitable mask for the wall area will not be. Once the mask is made the next step is an L channel Curve adjustment (vertical move of the Color Sampler point with the Info Panel as a guide).
Hi
This will work better on a higher resolution image but you can try the following.
1. Go to the Blue channel and use Duplicate Channel to make a copy of it
2. With just that channel selected use Image Adjustment Curves to bring up the contrast on that channel
3. Make a selection round the window and fill that area of the channel with black and the same on the door frame
4. Deselect and switch back to the RGB channels
5. With the image layer selected use Ctrl+J twice two make two copies of your image layer
6. Name the upper copy HF and the lower copy LF
7. Select the LF layer and use Filter Blur - how much depends on your image I used 2.7px on the low res copy - if you have a higher resolution then somewhere around 6 should work
8. Select the HF layer
9 Go to Image >Apply Image and set the dialogue as shown:
10 Set the blending mode of the HF layer to Linear Light
You will now have a greyscale layer with the detail (HF layer) and a color layer with the blurred color. The idea is to make changes to detail on the HF layer and to general shade and colour on the LF layer
11 Select the LF layer and with a soft brush Alt click on the wanted colour. Don't worry too much about the edges - you will use the blue channel copy as a mask later
12 Switch to the HF layer and use the clone tool (set to sample current layer) to clone out the join from your previous painting
13 Put the HF and LF layers in a group
14 Ctrl Click on the Blue copy channel to load it as a selection then in the layers panel click on add mask
If there is any fringing then Paint it out on the HF channel
Like I said, this will work much better on a higher resolution image but hopefully you get the idea
