color - modelint/flatland-model-diagram-editor GitHub Wiki
The color keyword is optional and specifies a background color for your diagram. In addition to making your diagrams look extra awesome, there are some practical benefits to coloring your background.
- You don't get bombarded with all those bright white pixels when your diagram is vividly displayed on an expansive monitor.
- When you are working with several models, a color coding system can help you quickly identify a particular diagram.
That said, background colors are problematic when you go to print hardcopy (anyone still doing that these days?) No worries old-timers. There's a flatland command line option that will turn the background color off so that you don't need to order another expensive toner cartridge after your A1 size printout completes in about three days.
color <color_name>
where <color_name> is a flatland defined color. You can use system defined colors, which can be viewed if you specify the -COLORS command line option. You can define your own colors by editing your color.yaml file
