yeah i see that but microsoft know's the most people they will get that for install in pcs or vmwares..
What's new in Windows 10 Insider Preview build 10525 - DEVELOPING Desktop New color options Edge Base for Object RTC support And further Improved memory management
Ah yes. Another method you could try would be to edit the registry, if you felt comfortable doing so. First choose the last color tile in Personalization - Colors. Then you would go to the following entry: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize There you would change the value of SpecialColor. For pure black it should be 000000. Save the change. You would then have to log out, then back in, to see the changes.
Yeah, that's getting the most comments by far re 10525 in the Feedback app. I'm a little surprised anyone has the RAM to run 64-bit Chrome. I thought 32-bit took all RAM, so 64-bit must take at least 2x that (OK, kidding, but why add insult to injury).
Ah damn. Only other thing I could think is if someone else here is more familiar with how to manipulate the msstyles file they could explain how to change that dark gray in that theme to pure black. Or possibly contact the creator of that theme to see if they would share how to do that. Sorry I couldn't be more helpful.
I think the problem is from Microsoft not developers...(i posted a feedback) i tried a black high contrast theme the pure black is there (everywhere ) but high contrast theme sucks
