VICE Palettes
If you look at paletes files in VICE they look like that
#
# VICE Palette file: PALette_C64_v1
#
# Syntax:
# Red Green Blue Dither
#
# Black
00 00 00 0
# White
FF FF FF F
# Red
8C 32 3D 5
# Cyan
66 BF B3 A
What is that Dither value, and how is it used? |

Seems not used anymore, from the old VICE documentation:
Quote:
4.3 Palette files
Palette files are used to specify the colors used in the emulators. They are made up of lines like the following:
RED GREEN BLUE DITHER
where RED, GREEN and BLUE are hexadecimal values ranging from 0 to FF and specifying the amount of red, green and blue you want for each color and DITHER is a 4-bit hexadecimal number specifying the pattern you want when rendering on a B/W display.
New vpl files don't have such 4th element. |

That value wasn't used for literally decades. In the dark ages, when displays had 16 colors, this was supposed to be used for dither patterns. I don't think it ever worked, at least i never saw code for this. |

1) Thanks for posting this. Pointed me in a direction that made me finally fix my VICE colors.
2) Color palettes are a biggish problem for the NTSC C64 art crowd. Every single game I tweaked the colors, brightness, saturation, and contrast for whatever looked best. When I create artwork and some websites change the palette to "give all artists an equal playing field" .. it's disappointing. It may be true that it allows the artwork to be viewed with consistency, but it's so often far off from the colors I was using during creation. </whine> |
