using two pallettes at once

[Frogblender]

I was wondering if there's some way I could assign a pallette to a certain location of the screen, or if there was a way to combine two pallettes. Here's my code;

disable screen
loadtiles blue,16,256
pallettes pallette1,0,0,16
i=256
for y=0 to 3
for x=0 to 3
drawtile i,x,y
i++
next
next

i=256
for y=4 to 7
for x=4 to 7
drawtile i,x,y
i++
next
next
enable screen

blue: datafile blue.dat,bin

pallette1: DATAINT $0A22,$0E88,$0A42,$0A44,$0E66,$0E68,$0E68,$0C44
DATAINT $0C66,$0C46,$0E46,$0A24,$0ECA,$0C24,$0C42,$0000

If you run this code with a 4x4 tile (blue.dat) you should see one blue square at the top-left and one immediately at it's bottom-right corner. I'd like to know if I can create another pallette and assign it before I draw the second square, so the code would create two differently-colored squares. I'm assuming the pallette command cannot be assigned to specific locations on the screen, so I was thinking that I could possibly treat the tiles as a sprite and color them that way. Any help is greatly appreciated.
(btw, this code is based off the "FF7 Slideshow" example that came with v0.12.)

each tile (tiles are at least 8x8) can only use one pallette at a time. this isn't a basiegaxorz limitation, its the limitation of the sega genesis.

however, there is a way to switch pallettes for tiles in when verticle blank occurs. this method is way too sophisticated for basiegaxorz b/c basic is slow and pallettes need to be switched fast.
