Image colors changing when importing and scaling - RAS88 - 03-20-2025
Hi everyone!
I'm having some issues with the color of my images, hope someone can help me.
I have basic knowledge of G.I.M.P., but I have been able to use it for a while without issues until now.
The issue is when I import an image (.png) the color is completely different from what it's supposed to be, for example a bright blue logo appears grey once imported, and I have to select some pretty extreme settings in the color filters to change it back to what it's supposed to be.
I used to be able to import any image (as well as this same logo on other projects) normally before and never had an issue, but I recently started to see this change in the 2.10 version, so I updated it to the 3.0 version to see if that fixed it, but I still get the same issue.
Also, I'm saving my project, and when I reopen it, some of the images appear distorted for some reason.
Any idea what might be happening? Is this a bug, or some setting I'm overlooking? Thanks!

Things to check.
What is the color mode of the logo ? Image -> Mode. If it is not RGB make it RGB.
Are you opening the logo over an existing image ? File -> Open as layers or maybe a copy / paste into. What is the color mode of the image, Is it Indexed or Greyscale ? Again change the mode to RGB.
Short explanation. There is coercion, The imported image takes on the property of the base image. Generally, make sure you work in RGB mode.

What are your color management options? Do you get questions about a color profile?
For the distortion, can you post before/after images?

The color mode is RGB, and I am opening the images as layers.

Which color management options do you mean? Where can I find them?
Haven't seen questions regarding color profile.
Here are the before/after images of the distortion:
Here's another example. I import the file with the golden letters, but it comes up with the red letters:

What we need is the original image, not a screen capture (because the problem is probably with the input image format). Screen shots are OK to show how it looks once loaded, but they should show the complete UI.

Mmm...How can I upload the original image with the 500 kb file size restriction? It weights 1.07 MB

You can put it on a service like Dropbox (wrapped in a ZIP to avoid re-encoding because these sites can be a bit cavalier with images) and post the URL here.
Otherwise see your PMs.

Ah, the usefulness of showing the whole UI in a screen shot...
The Union Jack image is color-indexed. This creates all sort of problems and explains the color shift when you add the other two images as layers.
No explanation for the washed out Union Jack. Look like some layer blend mode. Against, this is information that is shown in a complete screenshot.

OP should go back and read post #2
