How do I change the color of the vertical scroll bar on the right side of VScode?

Question

I used a dark theme, but it was too subtle!

Answer 1

You can customize your theme colors.

Press Ctrl+Shift+P to bring up the command palette and run the Preferences: Open User Settings (JSON) command. Add the following lines to your configuration:

"workbench.colorCustomizations": {
    "scrollbarSlider.background": "#ff0000",
},

This will change the scrollbar slider color to red. Adjust the colour value as you like. See more colour options for the scrollbar here.
