[Q] Looking for advanced color inversion without root - Android Q&A, Help & Troubleshooting

I know that Xposed has a module that allows you to invert system colors, as well as in other areas. What I am looking for is something that basically inverts all text to show white characters against a black background... but here's the catch:
I don't want to invert the colors of images, be them PNG, TIFF, JPEG, GIF or whatever.
It seems to me that color inversion is a wise way to save battery life, especially on an AMOLED screen, so why there aren't numerous options or apps to provide such a feature is kind of beyond me at the moment.
I have a Note 3, and there is color inversion, but I don't know anyone who wants to look at inverted pictures. Computer power users are all too familiar with reverse text being much easier on the eye and more legible. If I have to root, I'm not opposed to it, but only if there's something that truly allows you to invert colors system wide without inverting photos...
Are there any options out there that I'm missing?

[Q] How can I change the default background color (not the wallpaper)?

There are some apps that when they do not completely fill the screen, there is a default image on the Droid that fills the space.
In the two examples below (Chomp SMS and K9-Mail), the light grey area at the bottom is actually a fine pattern and not a continuous tone, leading me to believe that it in a stock image file.
Does anyone know how to change this image, or replace it with a solid color? Are there any themes that address this? I'd like to get it to be all black to blend with the color schemes I've chosen in the programs.
Thanks,
Chris
I'm with you, I'd like contact list etc to be white on black instead of black on white/gray

HTC eReader

Hey guys. Before the HTC Flyer, I use to use Aldiko and what I really loved about Aldiko was that I can change the margin size and font sizes more liberally than the HTC eReader. What I find annoying is that the eReader's margins are way too big, however I like the widget and the some of the other features, such as background page color. I was wondering if it is at all possible to decrease the margins so you can fit more text on screen.
If not, is there another eBook reader that provides a widget like HTC's?
Thanks in advance.
Looks like you can change font size, background color(white, light orange, light yellow, and night which is black with white text). I don't see a setting for margins, but the text size might be what you're looking for.
I know of those color page options and everything. I'm just looking for something that will change the margins. The font size, even when set to smallest, leaves quite a bit of margin-space and I feel I can fit more text in if I was able to modify that.
One of the benefits of the wider margins is that you can tap on links in e-books without turning pages. I run into that problem with some textbooks in other e-book readers (especially on my phone, but also on the Flyer.)
I agree, though, they are quite wide in HTC's reader. I haven't found a suitable alternative, either.

Why don't you continue to use aldiko? I know I do...
I like the widget for htc eReader. And with Aldiko, you can't change the the background color (or can you?)
I might end up having to use Aldiko, though.

You can change bg color in aldiko. No widget, though it has a shelf view.

[Q] Question about changing the Notification drawer color.

Well, went forum diving, saw a few methods of trying this, but it doesnt look like swapping PNGs is doing the trick. I'm pretty much trying to invert my systemUI notification drawer background from white to black, and needing to know which xml/smali I need to edit, because like I said above I've tried a PNG swap and it had no effect, so it makes me think there's a static color being forced through xml/smali.
Thanks for reading

Change lock screen text color

I have a HD7 and the lockscreen text is ALWAYS white even if you change the theme to dark. I wouldn't really care normally, but the text is hard/impossible to read depending on the background for a bright lockscreen background. I would just write an app to change it but there's nothing in the API to do anything with the lockscreen. So just curious if there is some other way to change this before taking other drastic measures.
as i know,there is no way to change it.maybe u can search the theme regs to find out if thereis a color code to control the text color.

Themes, and text bubbles messaging app

So, on my note 8, I used a them called (red) strokes. On the S10+ my text messages are white on teal, and the received are like white text with a light grey bubble, incredible difficult to see, and the background is white.
But that them includes the red keyboard...
So, is there anyway to customize just the messaging app background and text bubbles, and or the keyboard colors independently of downloading an entire theme?
Is there a way to modify my theme without somehow magically being accepted into the Samsung Theme developer thing that they have, to gain access to samsung theme editor?
Perhaps try a different messaging app? Android Messages is a solid choice with light and dark theme options. Of the third party apps, I'd recommend Textra or Pulse which have many options such as light or dark and accent color choices.
