English Amiga Board - View Single Post - I am trying to make my first GFX assembler code

I could get 248 pixel in horizontal line - it was rather easy. IMHO it is possible even with CGA card but I didn't try to get such effect with CGA or VGA...
I am very impressed by the Amiga's copper. It is a very interesting thing and a wonderful discovery for me.

But it arises several new questions. Please help me with them.
5) How many colors can Amiga 500 show? Indeed there is well known number 4096 but can the Halfbrite mode produce new colors giving 8192 colors?
6) What is the speed of copper? We can change color register per each line and this gives us 4096 colors without the HAM. If this is true then we can even change some color registers during raster line drawing. So how often copper can change a register during a raster line?
