Hi, can we see an overview of the numix dark before purchasing the whole package please?
Thank you! :)

Love this theme, but on Xfce4, is it supposed to have a titlebar background color that's the same as the highlight background color?

I'm using numix-themes on Arch Linux Xfce 4.10 with many 4.11 components (xfdesktop-devel, xfce4-settings-devel, xfwm4-devel, xfce4-appfinder-devel, xfce4-dev-tools-devel, xfce4-panel-devel, xfce4-session-devel).

The only way I can get a black titlebar so that it matches the black headerbar is to use black as the highlight color. I definitely don't want to use back as my highlight color.

Is this a problem in general with Xfce4? Do gtk3 themes have to always use the highlight color for the titlebar background color? I checked other themes I have installed, and notice that only the really old themes have different colors for the title than the highlight.

Please provide a suggestion as to what I can do to get a black background on the titlebar without having a black background for highlights.

I spent a couple days on this, but as soon as I posted the message above, I found the answer. I has selected the Numix style from the Xfce Appearance application, and thought that was all I needed to do. Just now, it finally occurred to me to look at the Window Manager settings, where it also has a Style tab with a list of themes. Now that I've also chosen Numix as the Theme in that Window Manager Style tab, everything looks great with the dark title-bar matching the dark header.

The best theme i've ever seen!! 真是靚爆了!!!!~~
Hello hello :D

I absolutely love your theme.

Just purchased it as well, hoping that the "As a bonus, you'll also get an additional Numix Dark theme with the purchase." was a theme without any borders - not even the white border on the titlebar! :D

But, it was not :(

Any plans to release such a theme, completely borderless?
Or maybe you have a suggestion I can try out to edit it manually to remove the titlebar border? :)

Nowhere it was mentioned that you get a borderless theme O.o

To remove titlebar border, you have to edit the metacity theme (the metacity-2.xml and metacity-3.xml files).
That is true, I just hoped there would be one :D

Ah, yes - I've tried to tinker the metacity-*.xml files, and so far only been able to remove the border around the whole window - not the border on the title bar :o

Do you have a more precise instruction on what I can edit to remove the border from the titlebar?
Hi Satya, first thanks a lot for the effort and commitment you put in your work both in The Shimmer Project and on the Numix one, I've been using Numix Gtk Theme and Numix Circle for a lon time, but with the first one and LO there is a problem with radio buttons/check boxes with do not appear until you hover the cursor over them, (I will post the link to the images for better understanding) also mention that this also happens with Bluebird, Greybird, Orion but not with Adwaita. Hope you can check it out
