Testkitchen / KitchenCI - How to change console output colors?

Question

In the present case Ansible is used with KitchenCI/Testkitchen.

Question: How can I control the color of the kitchen output?

I tried different coloroptions in ansible but for kitchen I didn't find any options, but this bugs me, especially if the color of the kitchenoutput turns darkblue suddenly.

Problem: The color of the kitchen-output changes, depending on ...I don't know...

(It doesn't change every run, but at some time, something initiates the colorchange and then it will keep the color for a while)

Sometimes it's an ugly pink:

Sometimes it's yellow, green or cyan:

... But most annoyingly, if it's darkblue, suddenly, and I can't read stuff:

Setup: i3, xfce4-terminal, zsh, sometimes in tmux, with echo $TERM # -> screen-256color

I think, if something in the folderstructure change, or something in the current ansible environment (the shell-options are always the same), e.g. if I clone the whole directory (at least thats where I recognized it last time). It can even be a different color if I change the directory in the "roles" directory. But all in all I can't point my finger at it and I would be glad for help.

If more Information is needed, I would gladly provide it.

Update: Maybe it's something in ~/.rvm/gems/ruby-2.5.1/gems/... Theres a lot of code regarding "tty"

This does not answer the question (that's still interesting! because I don't want the color to change), but targets the underlying problem, meaning the non-readablitity of the blue color.

The reason was the configuration of "xfce4-terminal".

In xfce4-terminal one can define the representation for colors in the right-click: 'preferences' > 'colors' > 'Palette'

If a background-color is set, that would conflict with the color "blue" (dark blue), the representation for the color "blue" can be change (e.g. to grey, or light blue, or everything else).
