Personally recommend red.
I personally recommend using red fonts for the factory name to look better. Because the red font looks bright and bright, it is very conspicuous when placed on the door of the factory, and people can notice it at a glance.
Notes on naming the factory: The factory name should be easy to read and remember. When naming the factory, be careful not to be too long, and it must be easy to read and remember. This will help spread the name of the factory and be easily remembered by customers; name it according to the characteristics of the factory. Every factory will have its own characteristics, so when naming it, it should be reflected in the name. This will allow customers to have a clearer understanding of what their factory operates. Therefore, when naming, be sure to pay attention to a suitable A unique name for your own factory.
