Ah, now we get it! So, I've been further even more decided to use 136 colors even go need to do look more as anyone can. Can you really be far even as decided half as much to use go wish for that? My guess is that when one really been far even as decided once to use thumbnail artwork even go want, it is then that he has really been far even as decided to use even go want to do look more like. Well, all in all it's just common sense. |

it's just mixing colors like checkers
1: Color 1
2: Color 2
12121212
21212121
12121212
21212121
12121212
21212121
12121212
21212121
and you have a mixed color. 16x16 there are 256 color combinations. but!
S: Solid Color (Original C64 Color)
X: Mixed Color
M: Mirrored Color (same color with inverted checker pattern)
+ 0123456789ABCDEF
0 SMMMMMMMMMMMMMMM
1 XSMMMMMMMMMMMMMM
2 XXSMMMMMMMMMMMMM
3 XXXSMMMMMMMMMMMM
4 XXXXSMMMMMMMMMMM
5 XXXXXSMMMMMMMMMM
6 XXXXXXSMMMMMMMMM
7 XXXXXXXSMMMMMMMM
8 XXXXXXXXSMMMMMMM
9 XXXXXXXXXSMMMMMM
A XXXXXXXXXXSMMMMM
B XXXXXXXXXXXSMMMM
C XXXXXXXXXXXXSMMM
D XXXXXXXXXXXXXSMM
E XXXXXXXXXXXXXXSM
F XXXXXXXXXXXXXXXS
Number of Solid Colors = 16
Number of Mixed Colors = 120
Number of Mirrored Colors = 120
Since mirrored colors are duplicates, there are 120 + 16 = 136 colors. |

There's also true color mixing when using different colors of with the same luminance:
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
which results in a slightly different color than:
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBB
AAAAAAAAAAAAAAAA
Although using the same colors :)

The downside with crosshatching is that you tend to get big color-differences depending on where on the screen you have it, resulting in horizontal stripes, often in blue-ish and yellow (when watching on a tube television at least)
"Waiting for inspiration" by Carrion (very nice picture otherwise) looks like a zebra. -At least on my tv's.
Do anyone know WHY it is like that? |

its related to the effect graham mentioned - also in a checkerboard pattern PAL effects apply. |

Here's a photo of a TV with a C64 connected, demonstrating the difference between odd/even mixing:
Rows 1 and 4 contain the plain colours. Row 2 is mixed with colours from row 1 on even lines and colours from row 4 on odd lines. Row 3 is mixed with colours from row 1 on odd lines and colours from row 4 on even lines. |

But I'm still puzzled by that hires thing. Here is a photo of a TV showing checkerboard patterns with light gray and white. The upper one starts with a white pixel in the upper left corner, and the lower one is inverted. (gray in upper left)
As you can see it alternates between blue and yellow for every character row. It is in fact exact every char even though the camera seems to bleed a bit too. And the lower one does the same, but the opposite way. This is not logic to me.. But I might just be stupid :)
(this pattern may also be familiar to some from the sky in mr sids version of canabalt) |
