Was talking with owellgi in the chat. He realized that the color channels have actually been jiggled around a bit is all.
In Photoshop or what have you, you need copy the contents of each Channel in this order:
Green -> Blue
Red -> Green
Alpha 1 -> Red
(This means copy the contents of the Green Channel into the Blue Channel, etc.)
Hey ive been trying to work this out for a few days now in photoshop CS6 and so far the only things i thought of trying are using the color mixer (Didnt work) and fiddling with the Hue/Saturation. (Didnt work)
I see theres a channels tab next to the layers tab but right clicking does not give me the expected options and i cant really seem to find answers about it in my google searches.
All of this for 2D backgrounds because i expected them to be easier to edit than 3D, At my level of skill with 3D anything, So hopefully you or anybody else can help! c:
Edit:
Well. after more searching i found a page on adobe talking about Enabling Multichannels.
Then after doing it the picture went from a Neon Blue to normal Colors. ;w;

If anybody runs into the problem i guess this might help. if people are still doing this, Now i just have to figure out if changing the entire picture keeps the channel colors the same or if i have to do more "Magic". UwU
