Mac Photo: color replacement brush woes

[VectorCat]

I selected the color I want to change to, have the color replacment brush selected, layer active..the brush should be changing yellow to beige. Instead I get a light green. 

Is this a feature or a quirk of the tool?  The name implies that the brush will re-color pixels to the color in the color selector.

thank you!

The tool should really be called hue replacement brush. It seems to act on the hue of colours more than replace colour. You could test this by creating a pixel layer above the image, painting the colour you are using onto the pixel layer and changing it’s blend mode to Hue, does it look the same or at least similar?

No. I painted a reddish-beige, tried to "color replace" it with red; result was a weak purple. I can see how this could be useful, but we could truly use a color replacement brush, as well.  In other words, a brush which would transform the color to the color studio color.

Here's an example of how replacement could truly be the ticket: I was trying to touch a yellow object out of a photo. where the yellow object was unobscured, this was easy, but where the yellow passed behind other objects, it is I believe diffraction which is responsible for the yellow bleeding into, or influencing the color of the what was in front. Being able to change those pixels to the color of the in-front object would have been more elegant than using the clone tool to not only change the color but also reconstruct the shape through hand brush motions.  

IOW: keep the pixels that are there; merely change their color to match the selected color...would have been the BEE'S KNEES!!

"the brush should be changing yellow to beige. Instead I get a light green"

I got nothing.
I filled a layer with yellow then i set the foreground colour to beige (#F5F5DC) and nothing hapen.

Then i changed the colour to a kind of green (#3BE12F) and then i saw a change.
Tried with white and also worked.

Some colours work others dont.
Maybe there is a logical explanation.

Right. As documented,

The targeted colour's hue will be replaced with the current Primary colour's hue, while retaining saturation and lightness values of the original pixels.

Strictly speaking, yes, the brush behavior is in fact committed to documentation:

However, what I'm experiencing in actual practice is that the hue is not changed per the color chosen in the color selector; rather a completely different color results.

That is the problem.

Screenshots, and (ideally) sample documents, would be helpful.
