I have a bounded solid color in a 16 bit prophotoRGB image in photoshop. I select the color using the select by color range. I open the color picker by clicking on the foreground color box, and type in the RGB values for the color I want to replace the select. Then I use the paint bucket tool to fill the area (or I may use the edit fill menu function). However, if I then check the filled area, sometimes the color values are different from the color I filled it with. Can anyone explain?
Possible things that could be affecting it: The file has a brightness adjustment layer; some of the fill colors this happened with were out of gamut (out of gamut warning showed in color picker).
