Colons in SGR sequences are not recognized

[ku1ik]

From https://wezfurlong.org/wezterm/escape-sequences.html#graphic-rendition-sgr (WezTerm):

There are a handful of additional SGR codes that allow setting extended colors; unlike the codes above, which are activated by a single numeric parameter out of SGR sequence, these the extended color codes require multiple parameters. The canonical representation of these sequences is to have the multiple parameters be separated by colons (:), but for compatibility reasons WezTerm also accepts an ambiguous semicolon (;) separated variation. The colon form is unambiguous and should be preferred; the semicolon form should not be used by new applications and is not documented here in the interest of avoiding accidental new implementations.

Programs running in Kitty terminal also tend to use : instead of ; for RGB color encoding.
