Not a clue how to set a specific color...

[56_kruiser]

I am wanting to change the larger rectangle to the same color as the smaller brown square. When starting, the larger rectangle is white. 

In the picture below, what I did was use the dropper to click in the small brown square (have tried multiple locations in it from the darker part to lighter part), then select the larger rectangle and change the RGB settings to the same as they are when I click on the brown square.

In the picture below is the resuslts of how the white changes based on the rgb colors after I clicked the brown square. It has not hint of brown at all.

Any thoughts on what am I doint wrong or misunderstanding?

You have one thing with a few shades of brown going to Black, and another thing with a few shades of brown going to White. The shades of brown look quite similar to my eye, so I have to ask if you are wanting the White to be Black?

Maybe a gradient map will do the trick

1. B&W adjustment 

2. match brightness / contrast

3. select 2-3 colors for gradient map

Neither of these shapes has just one color so I wonder if you have filled each of them with a different bitmap pattern via the Gradient Tool > Type: Bitmap option. If not, can you explain a bit more about how you got each shape to have more than one fill color?

It might also help if you could post a screenshot of the Layers panel or an example afphoto file.

I don't have that exact item now to show the layers panel, but there was nothing in the layers panel than the first capture.

So, for example, I just tried this: I did a regional screen capture of to top area, such as the attached image. So with the Recolor Adjustment tool, I can drage it for different colors that apply to the image, which changes all levels of that color fine, it does not just cover it with a block of the new color. What I'd like to do is to be able to do that to change the color to brown (or what ever color I want). But with my base knowledge, I can't achieve brown, as it is a combination of different colors which I can't achieve by dragging the Hue, Saturation or Lightness bars. or entering RGB, or RGB Hex humbers.

 

 

For instance:

 

If I enter 150,75, 0, I get this: on the image above:

 

Similar results if I try RGB Hex,

The difference is only lightness, not color (hue, saturation). Recolor will not help as it preserves the lightness.

Using curves or gradient map will deliver the desired result.

Thanks. I'll experiment with that.
