After spending many hours getting it the way I like it, I'd thought I'd share my customized look for winboard.
The idea was based off of a nice marble chessboard that I have here at home.
I used these tiles that I made from generic pictures of marble,
plus the Chess Leipzig font available at http://www.enpassant.dk/chess/fonteng.htm
Because black on black is impossible to see, I realized I had to change the color to something that stands out but is still recognizable as being black pieces. The arrow color however, I wanted to stand out but not be too jarring.
So here is what I entered into my winboard.ini
/liteBackTextureFile="marblew.bmp"
/darkBackTextureFile="marbleb.bmp"
/liteBackTextureMode=2
/darkBackTextureMode=2
/renderPiecesWithFont="Chess Leipzig"
/fontPieceToCharTable=""
/fontPieceBackColorWhite=#f4f4f4
/fontPieceForeColorWhite=#494848
/fontPieceBackColorBlack=#d1bdbd
/fontPieceForeColorBlack=#8d0e0e
/fontPieceSize=84
/overrideLineGap=1
......
/highlightMoveWithArrow=true
/highlightArrowColor=#181fa8
I have also been playing with the Xiangqi board and have been using a separate winboard.ini with a second winboard.exe in a subfolder with a shortcut to the main one. This was mainly because I haven't been able to find an alternative font for the Xiangqi pieces, (If anyone knows of any, please speak up.) and you can't change the colors for the default pieces. The result, of course, would lead to black pieces on black marble. So this is what I have.
As you can see, I went with a sort of jadish color for the darker squares which seemed to fit nicely.
The tiles I made can be found here (The white tile is the same as the other one)
For the arrow, I decided to go with bright green to match board better.
/liteBackTextureFile="marblew.bmp"
/darkBackTextureFile="marbleg.bmp"
.....
/overrideLineGap=2
.....
/highlightMoveWithArrow=true
/highlightArrowColor=#18ff39
....
Enjoy!
