What kind of file is it?
And what exactly do you want to change?
Too be completely honest with you I'm not sure what type of file and I want the eagle globe and anchor black but the background dark green
Don't see an eagle there.
So the file you uploaded here is the original?
In that case it would be a raster image and you need to edit that in Photoshop.
In Illustrator make a green square. Place your image on top of the green square. Copy your image a paste in front so you have two. Hide the top image. Select the green square and the image still on top of the green square.
Go to Menu>Window>Transparency. Click the Make Mask button. Deslect the Invert Mask check box.
Now Show All will show the original copy you hid earlier and should look like this.
And the eagle is on top of the globe, holding the ribbon in its beak.
Only thing I see is a Rorschach test
