How to change chronograph second hands color from blue to black?
 

I think I tracked the parameter to the menu.ini clock section, I just figure out the colors or the entry specific to the second hands.

There are some really nice chronograph skins that get ruined by the blue second hands.

Anyone know?

Not 100% certain, but:

In the folder <Mod>\Data\Menu\Skins\American\Gui There's a file called clock.dds. Open that up in an image editor, find the second hand, and recolor it black. I believe you'll find it colord white in the file. The game modifies the color (probably in the code), but if you change the color to something other than white, it won't modify it.

Make a backup before modifying it.
