I have read and looked at tutiorals and I just cant get it to work.
All I am trying to do is change the color of a gif and png. They are for a
website and I just need to change the color of the objects. That is all.
Any help in very simple terms would help
Simple method if you have very clean colors borders (no antialiasing):
1) Set the foreground color to your final color
2) Start the color selection tool (betwen the magic wand and the
scissors in the tools palette). Set the treshold to 0. Click any part
of the icon that is with the old color. This will select all the parts
of the image that have the very same colors
3) Start the bucket-fill tool (bucket icon). select FG color fill, and
Fill whole selection. Click somewhere in the selected areas.
4) Done.
More complex method that also covers anti-aliased border:
1) Menu: Colors/Color to alpha... Click on the color bar, and in the
next dialog use the color picker on a spot of the color you want to
change. This should replace the old color with a checkboard pattern
(this indicates the image has become transparent at these places)
2) Set the background color to your final color
3) Open the layers dialog (Ctrl-L or Windows/Dockable dialogs/Layers)
4) Add a new layer (right click and Add new layer), or use the icon with
the + at the bottom. In the dialog, use a fill t original oneype of
Background color
5) In the layer dialog, drag this dialog under the original one. You'll
see this layer through the holes punched at step 1) in the original
layer, in effect replacing the color.
6) You can then save the picture directly as GIF/PNG/JPG (Gimp will
flatten it automaticaly). Note that if at this point you also save the
picture as XCF you can produce other versions with different colors by
just replacing the color of the bottom layer.
Since I have often seen this question asked to match the color of some
background over which the picture appears, and even better solution in
this case is to save the picture right after step 1) in a format that
support transparency (PNG or GIF).
