SUMMARY I love the new ability in Plasma 5.25.3 to colorize either just the titlebar or the titlebar and toolbar together using accent color. However there's a limitation I noticed while setting up the color schemes to use it: The choice between the two depends on a hidden option in the color scheme which isn't visible in the scheme editor. STEPS TO REPRODUCE Easiest way I found: Copy both the Breeze Light and Breeze Classic color schemes that come by default, then in both enable the "apply accent color to (in)active window titlebars" option. OBSERVED RESULT You should notice that both themes tint the titlebar, but only the one copied from Breeze Light will also tint the toolbar. If you dig through the settings, you won't find any option that makes it be one or the other. I even looked at the scheme in a text editor and couldn't find exactly what determines it. EXPECTED RESULT There should be something that can be changed in the color scheme editor which lets you decide. IDEA AND SUGGESTION Considering another issue is you can't make a color scheme that tints the titlebar without enabling accent colors, maybe it would be a good idea to make tinting the titlebar an explicit option as well. A new scheme option "use titlebar color in toolbar" should suffice: This way you can also use it without accent colors and apply the color scheme's titlebar color to the toolbar even when the accent color is disabled.

Created attachment 150719 [details] Screenshot This is the difference I'm referring to just so there's no confusion. Both styles are great but the color scheme editor doesn't let you pick which it is, it's seemingly based on which color scheme you start from. You also can't get this effect without using accent colors from what I've seen, IMHO accents should only change the color being used but without being a dependency for applying different color categories to different elements.
When you use a color scheme with Header colors, the option in question applies the accent color to both. When you use a color scheme without Header colors, the option in question applies the accent color to just the titlebar. We need to change the UI text to make this clear. *** This bug has been marked as a duplicate of bug 455809 ***
