I'm using gdb on Fedora 32 and gdb prints information with highlight color.
However the color has less contrast for example dark blue text on black background.
How can I disable the highlight color?
Use set style enabled off to disable all styling, as the manual says.

I use two dropdown terminals in parallel: Yakuake and Guake.
When using Guake, the colors are way too dark, which makes much of the colored text unreadable because of insufficient contrast. The problem is most severe when displaying color #4 (dark blue) on black background (which is the default color ls displays directories with) or in Midnight Commander (default theme, dark blue background).
Yakuake displays all 16 colors correctly and the text is readable very well, the colored output of ls and Midnight Commander.
My OS is Linux 5.15.11-gentoo with plasma-5.88.0, gtk+-2.24.33 and gtk+-3.24.29. Here is my TERM setting in the environment:
TERM=xterm-256color
COLORTERM=yes
I tried all available Guake themes and all of them have horrible contrast. Either all colors are too dark, or the other way around - all of them are too bright. It seems Guake somehow compresses the color contrast.
I also tried defining custom colors, copying the color settings from Yakuake, but even though I set specific colors explicitly, the actually displayed colors were darker. I validated this with a color picker.
Changing the GTK Theme setting in Guake's preference tab General did not yield any success either.
The question is: Why does Guake alter the colors? Is there a way to turn this off and let it display the actual colors I specified? The problem must be with Guake or GTK because everything else is identical when using Yakuake (environment, Midnight Commander colors, ls colors, ...)
The following screenshots demonstrate my Guake Appearance settings:
And here is some Guake support information:

Thanks a lot in advance.
It turns out ls renders directories as bold font with the expectation that the text will appear in bright color. As explained by Guake developers this is non-standard behavior used with old terminals that did not supported fonts. Guake follows the ANSI standard and renders the text correctly.
The solution is to tweak the ls colors accordingly.
How to change indent guide color.
You need to edit the color scheme file for the color scheme you are using, and find <key>activeGuide</key> and/or <key>guide</key> and change the hex color value in the <string> node below it to the value of the color you desire. See How do I edit the Solarized (Light) theme in Sublime Text 3 for details on how to make custom changes to color schemes.
I want the color scheme to span completely across the terminal boundaries. I am using Color Scheme Scroller Plugin to switch between different theme. I have uploaded a .gif file so that you can clearly see what I want to get fixed. Vim colorschemes doesn't completely change the color of editor. There are some terminal color's borders left around the vim's overridden color scheme. How would I fix it.

You can't do that from Vim itself.
Terminal emulators use that padding to preserve readability when characters are displayed next to the borders of the window. The programs you run in your terminal have no knowledge of that padding and thus no ability to change it.
But you can read the documentation of your terminal emulator or take a look at its source code to find a way to enable/adjust/disable that padding.
FWIW, there's no way to change that in Terminal but it can be done for iTerm.
Alternatively, you could simply set the background color of your terminal to the one used in your vim colorscheme.
The image appears to depict behavior outside vim's control:
it is using a terminal emulator (could be xterm, could be some other).
the terminal emulator draws character cells on a window
those cells form a grid; the window may extend beyond the grid
the window can have a background color
the grid can have a background color
within the grid, most terminals provide some capability of drawing text with specific foreground and background colors
the grid can have a default background color which is not any of the specified colors
outside the grid, the window can also have a default background color
normally, the grid- and window-default backgrounds are the same
the window can be resized to (more or less) arbitrary sizes
the grid is constrained to exact character sizes
because of this difference, the window can have areas outside the grid which use its default color, and not match the grid's background color.
escape sequences which could affect the grid- and window-background colors are doing erases (see for example the ncurses FAQ My terminal shows some uncolored spaces).
though it is conceivable that erasures within the grid could affect those outside areas, doing that generally leads to odd visual effects.
I've been trying to get colourschemes to work properly in VIM (on debian) when using it over ssh with PuTTy as a client (from windows7).
Such code from theme hi Search cterm=bold does not work - words are not bold.
I have tried a lot of themes - and I have found no themes with bold words (but using gvim on windows gives me bold words).
I'd appreciate any advice.
PuTTY by default represents bold as a brighter color, but you can change that at Change Settings > Window > Colours > [ ] Bolded text is a different colour. From the help:
Bolded text is a different colour
When the server sends a control sequence indicating that some text should be displayed in bold, PuTTY can handle this two ways. It can either change the font for a bold version, or use the same font in a brighter colour. This control lets you choose which.
By default the box is checked, so non-bold text is displayed in light grey and bold text is displayed in bright white (and similarly in other colours). If you uncheck the box, bold and non-bold text will be displayed in the same colour, and instead the font will change to indicate the difference.
I'm using terminal vim with the solarized-light theme for both vim and my terminal. If I try and use for example a dark colour scheme for my terminal a dark border appears around my vim window as shown in the image below.
Is there a setting I can change to remove this border, or reduce its width to 0?
You can't do that from Vim and your terminal emulator doesn't expose an option for that either.
So… use the same background color.
Nothing to do with vim it's a terminal background. There's no simple solution. Use the same background color or change a font. Some fonts with certain sizes ideally fit into terminal width and height. Bitstream font works for me.
