Given a black and white image like lips, how would I get those in red?

Lips

I don't want to use global flood filling, because that may not consider alpha transparency correcly.

How would I do that with layers?

No matter what I tried, the transparency is always lost. Paint.NET answers only, please.

You can adjust Curves. Use it in RGB mode.

The tool allows you to adjust R,G and B separately or together. I removed the selection check from G anB and lifted only red. You can turn black to any combination of R, G and B by changing the place of the checkmark.

  • Oh dear, even without any layers! Thanks. – Thomas Weller May 27 at 13:49
  • Consider this only as a quick trick. It's useless if you want to insert easily more than one color. Your own answer doesn't have that limitation. It can be your basic tool to work around the lack of layer masks. – user287001 May 27 at 17:01

It's also possible with BoltBait's Paste Alpha plugin.

  1. Copy the transparent PNG to the clipboard
  2. Create a completely red layer
  3. Go To Effect / Object / Paste Alpha
  4. From the second dropdown, choose "Alpha channel on clipboard".
