Ok so this might seem weird but lets see if I can explain this.

This is the sig saved straight from my photoshop as a jpeg format.
and

This is the sig that I screen shotted in my photoshop put in paint and then cropped and saved as a jpeg.
So my questions is why are the colours so much nicer on the one from paint?
Can anyone tell me why photoshop is fucking my colours up so bad. Shouldn't the orginal be better, you can especially notice it in the magenta in the corners. Just open them side by side and switch back and forth and you will see what I mean.
