How can I change the default syntax coloring in ruby 3.0's IRB

Question

I'm very happy to be using the most recent ruby 3.0; as well as having access to the updated command-line interpreter, which does syntax highlighting and coloring.

However, the colors are a bit hard to see for me. How can I change them? The command line options for IRB allow me to turn off colorization with --nocolorize, but I can't figure out where the configuration files are that would allow me to change the defaults (e.g., to make the blue color lighter).)

Switching to 'Tango Dark' made it readable.

Here how the new Ruby 3.1 autocomplete feature looks like right now:
