helix background is grey in foot, black in kitty

[Schweber]

Summary

I've set the background of helix to black ("ui.background" = { bg = "black" }) and it works as expected in kitty. In foot the background is dark grey however.

On the left is foot, on the right is kitty:

If i set the background to grey ("ui.background" = { bg = "grey" }) then both kitty and foot show the same background color:

I've opened an issue in the foot repository but it was closed because allegedly it is no fault of foot. The background of foot is also set to black in foot.ini (it shouldn't matter though):

[colors]
background=000000

Reproduction Steps

Set the background to black and run hx in foot.

Helix log

This is a launch of hx in foot ending up with the dark grey background. I see no errors.
