BannerMeta lets you create custom flag designs for banners and shields. Each banner can have unlimited patterns and patterns listed first will show underneath patterns listed later.
Base color should be the first thing listed for a banner. It will be displayed as RGB. Base color will show below all patterns.
Note that on 1.13 and above, you don't need to specify a base color for banners, as banners already have a base color.
Patterns will be listed after the base color and will include the type with the color listed after a comma. PatternTypes can be found here.
An example banner:
- BANNER:13 1 basecolor:11685080 SQUARE_TOP_RIGHT:14188339
