I've selected a color range with Photoshops "Color Range" tool, but the selection is a bit transparent. I want to delete the selected color.
Probably because the black pixels are not EXACTLY the "same black". One is per example 99% of black and an other one 100%. So it's two different colors. These colors seems to be the same but they are differents. So you must add or remove colors like said here: https://helpx.adobe.com/photoshop/using/selecting-color-range-image.html
With "Shift", "Control" or "Alt" i don't remember, you can add or remove colors of selection.
