So say for example you have the edited image, when you save it photoshop most likely changes the palette so only the necessary colours are included. But then that throws off the other images in the firmware which usually share that palette.

An example 256 colour palette...


But if your image is made up of pinks, oranges and greens, the program might save it with a palette like this...


The only real way of sorting it out is to make sure all the mentioned images share identical palettes.
Hope that helps.
Thanks drippydonut, That really helps me a lot. Now I can make my own theme.

Copy all images that share a palette (the list is in the helpfile) into one
image in photoshop before editing. E.g.
- Create a new image 100x176 pixel, true colour, not palette based.
- Copy the images of a shared group into it, e.g. the Background Navi
Left, Middle and Right.
- Modify them at will, or draw completely new designs of the same size.
- Now reduce the colour depth to 8 bit, palette based.
- then cut the three images from the big one, they now all use the same
palette.
- save as gif files, to make sure that they remain 8 bit.
I don't have photoshop, so I can't give you details on how to do it, but
it should be easy enough, it is in paint shop pro.
Lord Julius Thanks for the tip. That was what I did at first. But my problem was finding the color table in photoshop CS2. Finally I found it in Image --> Mode ---> (choose indexed color) ---> color table . Now I understand that all images should have the same color palette.
I am really happy that both of you help me with this issue.

Thanks again.
