I used Adobe Photoshop, i am unsure about the workings of the software you have listed. However in Photoshop i just brightened the highlights a little, darkened the shadows slightly (made it a little more contrasty), added a small amount of saturation, and took out small amounts of red and yellow just to clear through the dirty colour that seems to give it that haze...oh, and i sharpened it just a wee fraction.
Most image programmes will have ways you can do this, but i can only really explain for photoshop. But i'm sure there must be someone in these forums that can translate what i did into a programme you have.
It's unlikely it would have lost it when you reduced the size of the image, but reducing sizes often does effect image quality but rarely colours. It may be something to do with the way your programmes talk to one another ie which colour calibration they all use (this is a very confusing area and one i don't really get). Sometimes after you have worked on or processed images and they look good, then you look at them on a web browser they will look different much the same way as when you try to print something and it comes out completely different to how it looks on screen. If you have used a few different programmes this could be the likely reason to why the colour may have changed.
Pointless waffle and not making sense is something i could write a book about....Sorry!
