I've been trying fine tune the colors on my fav theme moonshine.xml
I think there are a few issues with modifying such an old skin.
To name a couple:
You could add missing elements, but sometimes such elements depend on the existence of other elements.
And that is not documented anywhere.
The order of elements can play a role. Some will not work depending if they come before or after another element.
And that is not documented anywhere.
Also, I notice that that 'moonshine' skin is not properly following xml formatting rules:
To escape comments, it is often using two backslashes.
That is wrong, comments should be in the
<!-- comment --> format.
And there are even many comments in it that are not 'escaped' at all.
So, I think you are in for a world of hurt when trying to adjust that skin xml to your liking.
In my opinion the best way to go is to start with either the
Chameleon DNA or the Cheetah DNA skin.
It shouldn't take much time to setup the elements that are in the first section
<variables> so that the general look and feel resembles 'Moonshine'.
Next, you can edit the elements that are under
<colours> to finetune things.
I am convinced that this way of doing it will save you a lot of time and frustration in the long run.
