XYplorer Beta Club

In Tools|Configuration|Colors I set Inactive Pane Color to Black.
When application restart, color is always set to grey (#C6C6C6)

Do you save your settings? As far as I know XY doesn't save settings automatically. Most likely you have XY to work in tray all the time, and probably it hasn't a chance to close properly (with settings saved).

I save with File|Save Settings; I tried also File|Settings Special|Save Configuration and Save Folder View Settings

I open the Configuration File. I look for an entry for "Inactive Pane Color" but find none. Version # is 13.90.0100

Set the color to black and then type this in the addressbar: XYplorer will restart, does the color revert back to grey again?

Uhm, yes. Color black is 0 (zero), and in this context it also means "undefined, take factory default". So take a color near black (e.g. 010101) and all will be fine.

010101 works fine. Thanks to You all.

XYplorer is a great product. I gived it a try for 2 weeks and love it so I bought the Lifetime Licence Pro.

I know the poster got through this issue, but I'm wondering if this was the correct answer to the OP's question. While playing with theme scripts, I just experienced a similar issue trying to change the color of the inactive pane background and it simply would not change for me no matter how or what color I selected. As it turned out the setting, ShadeInactivePane=1 was set to "0" on this particular theme I was using whereas with other themes I have it checked off or set to "1". This setting is located under Tabs and Pane | Dual Pane. Consequently, no matter what you put in the box in Configuration | Colors for Inactive pane, the color doesn't show up. Are we sure that's not what the problem was here? That setting was never mentioned. I say this because inputting a color of "black", "0", either directly in the ini file or through the Configuration interface as "000000", hasn't been a problem in any of the theme scripts I've used.
Thanks,
Ken

You will note the difference after restarting XY...

[POST REPLACED]
this behavior isn't the same for all GUI-editable colors.

All set...I see what you mean as far as Inactive Pane Color not liking "000000". Thanks
