Here is a hint -
Three 24X24pixel monochromatic images
So, just create one 24X24pixel image that you want to put into Litewall with YY-CHR. Copy/Paste it until you have three of the exact same image. Use right click to select what you want to copy/paste.
Then replace the color in the images as follows
Black + Light Grey only
Black + White only
Black + Dark Grey only
Black = Background
Light Grey - White, - Dark Grey -
1L 4L 7L - 1W 4W 7W - 1D 4D 7D
2L 5L 8L - 2W 5W 8W - 2D 5D 8D
3L 6L 9L - 3W 6W 9W - 3D 6D 9D - Each these numbers represents 8X8pixels or a single right click selection. 27 sections total.
Now open the copy of Litewall you want to modify with YY-CHR in another window
Copy/Paste each 8X8pixel selection into Litewall
XX-XX-XX-XX-XX-1L-1W-1D-2L-2W-2D-3L-3W-3D-4L-4W
4D-5L-5W-5D-6L-6W-6D-7L-7W-7D-8L-8W-8D-9L-9W-9D - The XXs represent the black blank 8X8pixel sections. Leave these black.
These are all the 27 sections in Litewall with corresponding button combos - 8X8pixels each
