Is possible to change the color of the : separators in the hunk header?

[MartenBE]

I want to change the color of the : separators in the hunk header:

Is this possible somehow?

My current config:

[delta]
# https://github.com/dandavison/delta/discussions/2134
file-added-label = "+ Added"
file-copied-label = "+ Copied"
file-decoration-style = "#444444 ol ul"
file-modified-label = "~ Modified"
file-removed-label = "- Removed"
file-renamed-label = "→ Renamed"
file-style = "normal"
hunk-header-decoration-style = "#444444 ul"
hunk-header-file-style = "#444444"
hunk-header-line-number-style = "#444444"
hunk-header-style = "#444444 file line-number omit-code-fragment"
hunk-label = " Hunk"
hyperlinks = true
line-numbers = true
line-numbers-left-style = "#444444"
line-numbers-right-style = "#444444"
navigate = true
syntax-theme = "Visual Studio Dark+" # `#444444` is the bat color for grid.
tabs = 4

I don't think the : separators are independently styleable at the moment.

From the current option surface, the hunk-header knobs are things like:

• hunk-header-style
• hunk-header-decoration-style
• hunk-header-file-style
• hunk-header-line-number-style

but there doesn't seem to be a separate "hunk-header separator style" option for just the : characters.

So you can style the file part / line-number part / overall hunk header, but not only the : separator by itself.
