Originally created by @m4r1vs on GitHub (Oct 9, 2022).

Windows Terminal version

1.15.2712.0

Windows build number

10.0.19042.0

Other Software

Does not matter as this also happens with the terminal being freshly installed and independent of the selected shell (WSL, PowerShell, etc.).

Steps to reproduce

Change a theme's background colour to RGB(0,0,0) or create a new theme with pure black as the background colour.

Expected Behavior

I expected the colour of the background to be pure black.

Actual Behavior

the colour of the background being RGB(34, 34, 35). I had to create a pure black PNG and select that as my background image to achieve the blackness I wanted my terminal to be. It makes a HUGE difference, especially on OLED screens.
