Sets the colour mode of the terminal.

# Set:
Vedeu.configure do
  colour_mode 256
  # ...
end

# Get:
Vedeu.config.colour_mode

Note

• iTerm 2 on Mac OSX will handle the true colour setting (16777216), whereas Terminator on Linux will not display colours correctly. For compatibility across platforms, it is recommended to either not set the colour mode at all and allow it to be detected, or use 256 here.
