I noticed that the CMC prints messages to the terminal in a different color. I’m not sure if it’s because they are warnings or if it’s explicitly yellow, but, nevertheless, is it actually possible to use colors when printing (`ic_cdk::print`) to the local replica logs?

[Here’s](https://github.com/dfinity/ic/blob/master/rs/nns/cmc/src/main.rs#L430-L436) how the CMC defines its `print` function. It uses a terminal color printing crate called `yansi`
