First Time Modder, Issue with a Coral Island Re-Texture Mod

[VibingLemon]

Hi, I'm not sure if this is the place to ask (If it's not, please point me in the right direction.) and forgive for any lack of knowledge as I have never even picked up or thought of anything unreal engine related until this week

I'm trying to make a retexture mod for Coral Island to put my own art as a character portrait (EX of what this is SUPPOSED to look like) and I have followed my own modified versions of both these tutorials (1 and 2), with everything working out and even showing up as intended in game!

The only problem is the fact the image's colors and seemingly quality is all wrong. (PNG file VS In-Game)

I'm not sure what I did wrong or what the fix is so I'll detail my whole process below:

This is the setup I'm working with.

1. I put Coral Island into FModel and exported the raw data (.uasset) and texture file (.PNG) into a separate desktop folder.
2. I made my own customized texture file in Clip Studio Paint (with the same resolution) and exported as a .PNG file.
3. I opened up DDS Tools with the settings shown and put the corresponding .uasset file path in the 1st and new texture file in the 2nd section. Shown here. then injected it into a folder with the same path as the actual file's path in FModel (named "Wakuu-Retexture_P")
4. Used Unrealpak to make it into a .pak file by dropping the "Wakuu-Retexture_P" folder onto the unreal-pak-without-compression.bat file. Shown Here.
5. Added Pak file into the paks folder in the game's steam folder.

And that's it Any ideas what I did wrong? If needed here is a direct upload of the original texture file and the modded ones before and after all the steps.
