Hello, I use fvwm 2.5.31 on Archlinux and I have a colorset problem with FvwmIconMan. For exemple, if I use the PlainColorset option with a colorset with "#a1a4b4" as background color, the main background color of the buttons is set to "#50525a". If I use the option Colorset with the same colorset, it works as expected and the three colors of the buttons are : "#ededf2" for the light part, "#a1a4b4" for the main part and "#50525a" for the dark part. I have the same problem with the options : IconColorset, FocusColorset, FocusAndSelectColorset, SelectColorset. I have posted a small config file playing with FvwmIconMan colorset here : http://fvwm.pastey.net/144291 .
