  1. Greetings and Thanks.

     

    Please see attached.

     

    Layer 2 is a copy of Layer 1 and they look identical when one or the other is turned on.

    But when both Layers are turned on, then the pixels get darker as if the shade/color of the individual pixels are doubling up.

    I assume this has to do with the Antialiasing setting, but my brain does not compute.  Can you please tell me why this is happening?  Details in attached.

     

    Also, can you please recommend a YouTube tutorial on understanding Antialiasing?  I keep losing image quality and don't know why.

     

    Thank you,

    Dave the Newbie

    Hi Dave - welcome to the forum :)

     

     

    1. Yes. Use the magic wand tool :MagicWandTool: with the Shift key held down when you click on the target color. The Shift key enables a global selection, this means every pixel in the layer that is within the tolerance setting is included in the selection.

     

    Once you have cast the selection press Ctrl + C to copy it, then Ctrl + Shift + V to paste it into a new layer.

     

     

    2. Yes. First merge the two layers together. This is temporary - we'll undo it later.

     

    Next make a selection inside the fill area with the magic wand tool. :MagicWandTool:

     

    Go to and click Edit > Copy Selection

     

    Press Undo twice (Ctrl + Z twice also does the job)

     

    Add a new layer to the image :LayersAddNewLayer:

     

    Edit > Paste Selection pastes the previously copied selection into the new layer.

     

    Press Backspace to fill the selection with the Primary Color

     

    Now you can fill the selection with any color you like using the paint bucket :PaintBucket:

     

    Hello and thanks so much for your reply.

    Can you maybe answer another or should I start a new post?

     

    In attached zoomed-in graphic, I'd like to change every pixel that is not blue (i.e. all grey scales) to black.  The background is pure blue.  How can I select every pixel that is not blue and change all pixels to 1 color?

     

    Thanks again, very helpful.

    Grateful Dave
