I think you can use Sprite.a
Idk much about this...

Edit: I just realized that the program wouldn't run because I forgot to add REM before a comment >U< sry I have a fixed version now

kinda forgot how the bits work but:

it says that the palette is bits 0-2 of SPRITE.A. if this does mean the three biggest bits then you probably only need to do
SPRITE.A(n)\32
(n is the sprite number)

if the bits 0-2 are actually the lowest bits (the correct one) then its just
SPRITE.A(n) MOD 8
or
SPRITE.A(n) AND 7

(Edit: bits 0-2 are the three lowest bits)

Bit 0 is the low bit of a byte, bit 7 is the high bit of a byte, so MOD 8 or AND 7 is correct.

I actually had a bit of trouble finding a good source for bitwise annotations. Check this out - middle of page 4 - unfortunately it's a PDF not a website:

If I understand you correctly, you want to be able to print the palette number in use and in that case, you can make the palette the number a variable e.g

LET P = 2
PAL P
PRINT P

In that case, “P” is the palette number.
