How can I change the color of a text that is part of an image in GIMP?


Question

Please excuse the simplicity of my question as I'm new to image editing:

I have an image with some text and I would like to change the color of that text. I don't have the original file; I only have this image file. The text is currently white, and I'd like to change it to red or black, while keeping the + symbol yellow. I've posted a screenshot of my view in GIMP as well as the actual image file.

I somehow thought that I would be able to add a layer of red or black on top and the text would magically fill in and change colors, but that didn't work.

I did take a look at this question: How can I change the color of images in GIMP?

I'm went to colors --> hue-saturation but I could only change the color of the + symbol; "mathematics" stayed white. I tried changing other colors settings, but couldn't get the white in my image to go red or black. The darkest I could get was dark grey, but that's because I decreased the lightness. I could not get it to go solid red or solid black.

I'd appreciate and suggestions and/or solutions. Thank you!

1- Isolate the '+' symbol in your image using a free hand selection (Ctrl+wheel to zoom in/out to help you selecting), ctrl+x to cut your selection, ctrl+v to paste it into another layer.

2- Go to your layer containing the 'mathematics' text, lock alpha channel for this layer, now use the bucket tool to fill with any color you want, it will only affect the text inside the layer and not the entire layer thanks to the lock alpha option.
