Ubuntu 18.04 File manager app hard to read columns

Question

After upgrading to 18.04, I noticed that when I opened the Files app, the columns such as Size and Modified are displayed with a gray font that's hard to read sometimes. Is there a way to darken these letters to normal black?

Answer 1

they can be changed to black color.

but the simply way is to try some GTK+ themes from gnome-look.org website or from the default themes that comes out of the box in Ubuntu 18.04.

I have changed the color to black with the default theme "Radiance" that came up with Ubuntu 18.04 in the below way.

in order to change it. First you need to know which GTK+ theme is being used. to know that open Gnome-Tweaks application. if not yet installed, install it by the below command sudo apt update && sudo apt install gnome-tweak-tool or simply search in Ubuntu Software as "gnome tweaks".

Open Gnome Tweaks, look for the name of theme under Appearane-Themes-Applications

in my case i selected "Radiance" as my GTK+ theme, so when i open file manager, it looks like this.

now open the folder sudo nautilus /usr/share/themes/ look for the folder "Radiance" Open it and find the file nautilus.css in sub folder of "gtk-3.20" under "apps" folder.

Open the file nautilus.css and find the section at the top of the page

nautilus-desktop-window.background:backdrop,
.nautilus-desktop-window.background:backdrop {
    box-shadow: none;
}

.nautilus-canvas-item {
    border-radius: 5px;
}

.nautilus-canvas-item.dim-label,
.nautilus-list-dim-label {
    color: mix (@theme_fg_color, @theme_bg_color, 0.50);
}

.nautilus-canvas-item.dim-label:selected,
.nautilus-list-dim-label:selected {
    color: mix (@theme_selected_fg_color, @theme_selected_bg_color, 0.20);

and change it like

nautilus-desktop-window.background:backdrop,
.nautilus-desktop-window.background:backdrop {
    box-shadow: none;
}

.nautilus-canvas-item {
    border-radius: 5px;
}

.nautilus-canvas-item.dim-label,
.nautilus-list-dim-label {
    color: #000000; #here you can put any color you want
}

.nautilus-canvas-item.dim-label:selected,
.nautilus-list-dim-label:selected {
    color: #000000; #here you can put any color you want
