Color problem..

[DiamondTH]

Hey guys, well I have this color issue and its pretty annoying. I dont know if its something that can be fixed either. No one that ive talked to really knows why this happens but i figured id give it a shot and see if anyone here knows about this. Well, the first thing that happens is when i use clouds they dont come out black and white like they should its more of a brownish ugly color.



The second thing that happens is when i save my sig the color doesnt come out the same as it looks in photoshop. I save it as jpeg with the quality at 100%.

My sig in photshop:


Sig after i save:


If anyone knows how i can fix this please help me out! Thanks...
