Hi Every one=20
=20
I'm new to the web and Euphoria programming although I have dabbled in =
other languages, dare I mention 'C' <g>. I am currently working on a =
mode 19 (256 colour) sprite editor. One thing that puzzles me is there =
is only 247 colours, as the program below demonstrates. Dose anyone know =
why this is? And is it possible to get the remaining 9 colours?
=20

include graphics.e=20
include get.e=20
if graphics_mode(19) then-- 256 colour mode ?
end if=20
for colour =3D 240 to 255 do
        text_color(WHITE)
        printf(1,"\n%d%s",colour & "=3D")
        text_color(colour) =20
        puts(1,"*")
end for           =20
                       =20
if wait_key() then
end if=20
if graphics_mode(-1) then
end if         =20
--End of program--=20
