Alright, I have to fix this mystery once and for all. I do not know what else needs to be done in order to fix this issue, however when I save my images in Affinity, they turn into a completely different colors when I import them on other programs such as a video editor.
Now I open the same image and save it as the same file from Adobe Photoshop, and the colors are kept as the original (how it should look)
Video demonstration of what I mean
