Hi,
But what about when the operation takes place on the same layer? When the color I want to reduce opacity is not isolated on a layer, but is part of the image?

01 - In this situation, reducing the opacity in the layer will reduce the opacity in the entire image and not only in blue (desired color)

02 - Trying to get 80% opacity in a blue that is part of the image, I tried to use color to alpha, selecting the desired color and adjusting the opacity to 20% and the Opacity Threshold to 0 (zero), but the result is 100% opacity and not 80%.


One solution is to use a mask, adjusting the layer opacity to 80% and correcting the opacity of the other colors by adjusting the bottom layer.

Is there any other way to be able to adjust the exclusive opacity for a color or selection in the same layer?
