High Resolution Mode
|The high resolution mode on the C64 was 320x200 pixels,
which would be considered low-resolution these days. The computer used a
colour attribute system, which split the screen up into 40x25 columns of
8x8 pixel attribute squares. Each square could have two colours, a
foreground and a background colour.
Not many artists used this mode as the 'hi-res' graphics tended to be a bit blurry on a TV, resulting in unsightly image artifacts, also without very careful drawing the dreaded 'colour clash' would rear its ugly head.
Because of the limits you had to minimise your use of colour,
and space out your coloured areas so they didn't interfere with each
other, which resulted in either monochromatic pictures, or pictures with
separated areas of distinct colour.
