[Solved][1.19.3] How do I create multicolored components?

[Lucie]

For example, how could I combine a "Hello" with ChatFormatting.RED and a "World" with Chatformatting.YELLOW into a chat component looking like this: HelloWorld?

MutableComponent.withStyle() and related methods.

As you could easily find out for yourself if you used your IDE to search for uses of ChatFormatting.RED. e.g. ItemStack.getTooltipLines()

I had open the MutableComponent's class before posting the thread but looking at that implementation to create multi-colored lines seemed messy and unofficial, but ill take it if it's the only option. 

ItemStack#getTooltipLines didn't help this case so much but thanks for trying!
