Everybody: thank you for the help! I am testing now. It is difficult to make a smooth pallette with blue bit difference, but trying... thanks!

One more question. How could I read the value of a pixel stored in second page of Screen 8 mode? What is the start address for this page? Thanks!

Oscar,

VRAM page is stored:
32kb blocks on SCR 5 and 6: page*32768+address
64Kb blocks on SCR 7, 8, 10, 11 and 12: page*65536+address

Or you can use COPY command to access it:
copy (coord x, coord y)-step(width, height),page to (coord x',coord y')
