you're partly right, i used the color for button face background in primary substyle (light skin),
but for dark substyle i have changed it, it doesn't seem to have any effect.
I'm not partly right.
I'm either right or I'm wrong.
Original 1328 x 632
i know you're right but in this case unfortunately doesn't work, dunno why.
i deleted the light substyle, rename the dark sub, save it as a single sub wba, change to other skin,
delete style, apply the new renamed wba, and.... no effect, even reboot the computer has no effect, even change the color palette in light substyle didn't work, strange
edit: change picture to include the windows properties.
