ValueError: "blue" isn't a valid color - color_interface is not working

Hi,

I came across an error while editing my configuration file for nyx. When I choose the color "blue" as shown on the NYX-configuration page as an exsample, the error ""blue" isn't a valid color" is recived.

In fact none of the colors for "color_interface" work.

Configuration file /home//.nyx/config/nyxrc

graph_stat bandwidth
graph_bound tight
max_graph_width 200
show_interpreter false
connection_rate 10
#acs_support true
color_override blue
#color_interface false

Error from python3

Best regards and thanks for the good work.
