Are there any iOS SSH terminal apps that support truecolor (i.e., 24 bit color)? There are quite a few capable SSH terminal client apps in the App Store — Termius, Blink, Prompt, etc..

Do any of them support truecolor? This is also known as 24-bit color. It represents millions of colors as opposed to 256 colors.

As far as I can tell, this gist on truecolor has the closest thing thing I can find to a current, authoritative list of which terminal clients do and don’t support truecolor. I don’t see any iOS SSH clients on that list, sadly.
It turns out Termius supports 24-bit color, as does Secure ShellFish
