New to all of this, Perhaps I am trying to go about this the wrong way.....not sure.
But, for instance, suppose I wanted to cut an image of somebody out of picture "A", and insert it into an already existing image "B"
SO, I painstakingly draw a white area all around the perimeter of the desired target image, then extend that white area sufficiently large that I can select and crop to a rectangular image for use.
Then I review the image and find a color not in use in the target image, say HTML color h1cf905 for example ....no sign of that color anywhere in the target image , and then change the white area surrounding the target to that color, and then set that color to alpha.
Hoping to paste that image, complete with the transparent surround, into the "B" image.
Except when I set the surround color to alpha, it's causing the colors in the target image to get all whacked out. For instance with the color mentioned set to alpha, everything is shifting into violet colors.
Almost seems like the "color to alpha" function isn't discriminating properly, and is perhaps shifting all greens to alpha?
Thanks in advance for pointing me in the right direction
