It could all be grey and neutral but when you change the .gif at the top right to the latest Dokkan fest card you could also change the background shade to the Type that the card is.

e.g Coora would have been a shade of blue background.

That way the grey tabber will be seen easier against a "type" colour background. I used to do it all the time. Just like you do with the buttons too.
