When I use the color picker to pick a color image changes color!

Recommended Posts

Posted (edited)

Am I doing this wrong? I want to change the black color in an image to transparent.

On Affinity Photo macOS, when I go to color picker, click drag, it instantly changes the color tone of the whole image, which is not what I want. 

Just clicking on the image with the color picker tool selection changes the hue of the whole image...

I just want it to put the color in the color well. Why does changing the color in the color well change the huge of the whole picture if the layer is selected?

I don't know what's happening.  Is that a bug or something I don''t understand? How do I prevent that behavior?

For example, original:

What it changes into after finishing color selection:

Try this,

  1. Invert layer (⌘+i)
  2. Filters > Colours: Erase White Paper
  3. Invert layer (⌘+i)

Should end up with something like this.

As for the original issue I can't replicate what is happening.

  1. I select the layer in the layers panel
  2. I select the colour picker tool (i)
  3. I mouse over a corner area of the image and Left-click, hold and drag
  4. All that happens is the colour picker adds the colour to the colour well

If you have an (Image) layer, and you're using the Color Picker Tool (as opposed to the eyedropper in the Color panel), then make sure you do not have "Apply to Selection" enabled in the Context Toolbar:

Another way of doing something similar to what firstdefence said is simply putting the layer mode to 'screen'. This makes the darker shades transparent leaving the lighter shades opaque.
