Hi,
So basically what you'll need is some code to change the palette when you go to that specific card, and change it back when you leave. This could be done in the button code or in the "on view" of the card. The "all about color" deck does have a bit of example code for doing this on the palette transitions page.
My palettefade module may be handy too, although it's primarily designed for doing fancy fade in/out transitions it does have some helpful utility functions for changing the palette. Hopefully should all be in the documentation but I'll try to go over some examples here.
So if you're using palettefade and you've added the module to your deck, you can get the current palette as a list of 16 integers by running pf.currentpalette[deck] in the Listener. Generally I'll take the output of that and make them like global constants e.g. in the deck-level script I'll have palette1:(16777215,16776960,16737536.... and so on for the various palettes I have.
Then when I want to change to a certain palette I'll use pf.setpalettte[deck palette1] and that'll change the palette. So I can have that in my "change to a new card" button or just in the "on view" so that however you got to the card it'll be at the correct palette.
If you want to get fancy then you could use the blackdip function in palettefade, that does a nice smooth fade to black and then fades up with the new palette, e.g. pf.blackdip[deck card2 30 palette2]. Or you can do something with transitions like in the all about colour deck example.
I hope at least some of this makes sense. Let me know if you're getting stuck though.
