Complete Colour Change in Image/s

2 questions,

do your images have embedded ICC profiles?

are you using the same display screen and settings?
even better is the display system calibrated and profiled?

I see the skin is rather pinkish in image 2, that looks to me like an sRGB image with Adobe RGB used to display it, try edit/assign profile and assign sRGB, any better?

For images without an embedded ICC profile, by necessity an ICC profile has to be assumed so it can be displayed on-screen -  Photoshop uses the default RGB colourspace (ICC profile) as defined in Photoshop's Color Settings

I hope this helps

Are you sure you edited 2585 to match 2570 in appearance back then? 

Did you change your RGB Working Space since then? 

Please set the Status Bar to »Document Profile« and post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible? 

What are the images’ embedded ICC Profiles? What are Photoshop’s Edit > Color Settings?
