You are doing fine don’t worry 
For the colors, yeah the real Super Famicom/Eur SNES (and not ugly american SNES colours 
) are probably the most used, Microsoft copied it, and even Sony to some extend.
But it would not be a problem to make your own distinctive scheme!
I’m sure some STL files will appear for printable buttons ;). Heck I might even learn how to actually model something for my 3D printer and do them myself lol.
I was thinking about swapping the buttons too, is there a way to map the new positions so that it works with clockworkos? (worst case I’ll just get used to hitting A when asked for B, etc.). I know it’s easy to do in retroarch but curious to see if it can be achieved for the OS too. Thanks 
There is an option to swap the buttons under Settings in the launcher menu. Make sure you have updated to the newest version of the launcher though.
Oh, I just needed to upgrade. Thank you so much! What an easy and visual way to do it, already love this little device!
The Lightkey has four additional buttons (2L & 2R) plus and additional Shift button in the center,
