Output more colors in the VGA palette #17

SleepMod commented 3 years ago

I have taken a look on the code "VGA/kernel_c/Simple/vga.h" and its what i was looking for graphics design, but i see they are predefined 16 colors when the resolution is 320x200 (known as 13h mode), so, i changed the color output and making changes up to 0 - 256 colors palette, instead of using the vga.h colors. But the colors are not displayed. How do i implement them, or its set up in mode AL = 0Dh, instead of AL = 13h?

well you can assign numbers till 64 for different colors, the names provided in vga.h file are standard as available since DOS. check above link code, if you can find other ways to add more colors.
