We can at least investigate the option to adapt color taken from wallpaper. It would match the same color which Windows is using for draw around windows. See screenshot for comparison with Excel mobile.

I don't think we'd want to take a color from the wallpaper, because the window would tend to get lost against it. A contrasting color might work. This is definitely out of scope for the near term, and kinda feel more like addon material. [Do the Office apps actually adapt their color, or just use a static color?]

Static. Word use blue, Power Point orange, etc. Anyway, Win10 calculates the color differently. It doesn't extract the one with most coverage, but the most contrast one. Taskbar and Start menu looks really cool with it.

Or we can use just orange, since that is FX's color.

(In reply to Peter Henkel [:Terepin] from comment #3) > Or we can use just orange, since that is FX's color. Using orange looks really flashy. About the wallpaper color, if we do this, we can only get less native, since most apps don't do this, only Phone Companion does this as far as I know. Philipp, thoughts ?

I meant dark matte orange. Power Point doesn't look flashy at all. Current grey mixed with orange, perhaps?

I'm generally cautious here, since this could end up being very in-your-face. It is also getting very much into the territory of lightweight themes. However, in the spirit of due diligence: is there a single spot in the CSS where the gray is defined, so I could experiment with a few colors?

Two words: private browsing. ;)

How things currently look for reference.

Using about:preferences's sidebar color

Official Firefox identity color

A paler orange

darker orange

I honestly think orange doesn't look good here. The Project Chameleon navy could work, but it can be mistaken for private browsing.

I think your dark orange is not dark enough, picking something from the fox tail could work better, something like C14217 (just one of the many)

In my opinion, gray is still the best color here. Looks very clean. I put up a simple userstyle that allows you to change the titlebar color : https://userstyles.org/styles/116776/windows-10-colored-titlebar

(In reply to Marco Bonardo [::mak] from comment #19) > I think your dark orange is not dark enough, picking something from the fox > tail could work better, something like C14217 (just one of the many) That looks even darker than PowerPoint's orange, almost looks red.

(In reply to Tim Nguyen [:ntim] from comment #21) > That looks even darker than PowerPoint's orange, almost looks red. That was the point! If you look around for firefox wallpapers, you will find most use this kind of dark orange-red color, rather than a light orange, for good reasons.

Microsoft added option to show color in titlebar, so we really should stop forcing our own color. We didn't force it in Win8, so why start now?

(In reply to Peter Henkel [:Terepin] from comment #24) > Microsoft added option to show color in titlebar, so we really should stop > forcing our own color. We didn't force it in Win8, so why start now? Yep, see http://www.neowin.net/news/here-is-what039s-new-in-windows-10-build-10525 . We should simply go with the system setting, we can't just force color when the user has chosen not to have some. Let's keep the gray color when the setting is off, and use the color when the setting is on. Philipp, thoughts ?

I'm going to forward dupe this to bug 1196266, since this bug has wandered a bit, and the other is a more-succinct summary of where this one has ended up at.
