However, when querying stdout in a Pluto cell, :color is set to false, so well-behaved Julia code will not print colors. MWE: printstyled("hello"; color=:red). A workaround is to wrap stdout in your own IOContext and set :color => true, but this should not be necessary.
(Please take this screenshot in place of a video. Nothing dynamic here.)
Since #2148 the
stdout
capture window supports ANSI terminal colors, and:color => true
is set indefault_stdout_iocontext
as seen here:https://github.com/fonsp/Pluto.jl/blob/216451c3c839d1c3c6c50a0b69ba1b8297cceb43/src/runner/PlutoRunner/src/PlutoRunner.jl#L1007-L1012
