Package: dpkg Version: 1.18.23 Newer versions of dpkg have colourized output.
I can see the usage case for this, and I can see the value for some. However, for others, it is a major detractor. One of the issues with the recent colourization of the userland, is that each has its own way to disable it. Which is why /etc/terminal-colors.d/disable exists, as far as I can see. Yet, dpkg does not respect /etc/terminal-colors.d/disable. dmesg does. Lots of other packages do. I'd ask that dpkg respect this. It provides a single place to set to set that option.
