What's your OS? What's your RStudio version? What's crayon's version?

What's the output of

crayon:::detect_tty_colors()

What's the output of

system("tput colors 2>/dev/null", intern = TRUE)

from crayon.

Sorry, that was really bad GitHub etiquette on my part.

I'm running RStudio 1.4.1106 on Windows 10 build 19042. This is R 4.0.5 and crayon 1.4.1.

Both crayon:::detect_tty_colors() and system("tput colors 2>/dev/null", intern = TRUE) return 256 in RStudio's terminal.

I ran through num_ansi_colors() with debugging and none of the if statements were true. This meant it went to the last condition, running detect_tty_colors(). In detect_tty_colors(), the condition os_type() == "windows" && win10_build() >= 16257 was true, which returns a hardcoded 256L.
