Linux Mint 19.1, white text on white background - gtk

I am having some problems with Linux Mint 19.1 (cinnamon edition), which shows some texts in white on white backgrounds.
This issue happens for example in the logs of gnome-builder or in the selected items in gnome-boxes:

Using a dark theme (currently using 'Vivaldi') "fixes" the issue

Colored emoji in VS Code Windows 7

I'm trying desperately to display the colored emoji in VS Code but it's impossible. I am using Windows 7 and the emoji appear in black and white.
I tried the Emoji extension (support for Windows 7) but it's even worse because the emoji disappear.
Isn't there a simple solution to do this? Maybe there is a font problem but my emoji appear in color in Firefox.
Windows 7 does not have colour font support. That was added in Windows 8.1.
Note that Windows 7 is no longer supported by Microsoft, as of January 2020: https://www.microsoft.com/en-US/windows/windows-7-end-of-life-support-information

DBVisualizer background colour

I have DB Visualizer 9.5.7 on Windows 10 64-bit, using Java 1.8.
I am not able to change the 'Normal' Background Color from the default White to another colour such as Grey (for example).
I am using the Free version.
Should this work?
Thanks!
no this will not work, you need the premium version to do this.

How to change the background color of Meld?

I have Linux Mint 17.3 Rosa - Cinnamon as OS, the desktop is Gnome, and the toolkit is GTK 3.10.8 and GTK 2.24.23.
I would love to change the background of Meld to a darker color.
I followed these instructions: https://wiki.gnome.org/Apps/Meld/DarkThemes, and the outdated technique (with a /.gtkrc-2.0 file) changed the colors what Meld use, but not the white background color. There is no variable in it for that.
I tried to create/change desktop themes as well, but I was not able to change the background of Meld (but I do not know anything about Linux Mint themes).
Any ideas, how could I change it?

Eclipse color Message Box

I've downloaded eclipse Mars 64 bit for Linux and there is a very big problem. When I want to take a look at warning, or error messages I get a dark brown box with black text. I don't know where to change this color.
What I've just tried:
window-preferences-java-editor and changed all colors.
window-preferences-Appearance-Colors and Fonts and changed all dark colors.

Eclipse change color of vertical white line

I've applied a custom code coloring theme to eclipse 4.3 (Kepler), but there is this annoying thin vertical white line separating code and line numbers. Is it possible to change it's color somehow?
I'm on Ubuntu 13.10 (Saucy Salamander) 64bit, Java 1.7_45 64bit
UPDATE: I've installed Chrome Theme which allows certain customisation, so I was thinking maybe there is a css to change that line color?
That white (it's not white actually but #F8F8F8) line was haunting my dark theme. Google sent me here but couldn't find a working solution. But I found some clues as to where to look for a solution. If you're running Eclipse on Windows 7, there's a file called e4_default_win7.css inside one of the folders. Just search for it.
In that file the last section is,
CTabFolder Canvas {
background-color: #28446a;
}
Just change the color there. That'll solve the problem. I actually did this for my TrueStudio Eclipse IDE. But this leaves another problem. The text is too close to the line numbers and I don't know how to change the margin between them!
