Deno.colorDepthto get the color depth of the tty. It detects the following color depths:1bit: black & white4bit: 16 colors8bit: 256 colors24bit: 16,777,216 colors (often also referred to as "true color")This mirrors Node's
tty.getColorDepthvalues which we already support.Not sure if we want to add it or not, but I figured having a PR up might be nice. Idea came from #27866 where environment var permissions are mostly from color libraries trying to determine the currently supported color depth.
