(I lost the source code)
Drag and drop files and folders onto exe file.
This will remove the color 0x000084FF 
To use this program with another color,
create a file called "newColor" in the same directory,
and add a hex color in the format of [RRGGBBAA].
This program will overwrite the originals by default.
To disable this, create a file called "keepOrigin"
This will create new images in the same places with the same name,
but with "-b" added just before the extension.
