[SOLVED]Question about the ResourceBundleTranslation?

How can you load Text Placeholder or Text Colors?

I’m not sure what you mean. Could you provide a bit more context as to what you’re trying to do?
If you want to obtain a TextColor instance, use the TextColors class and for Text.Placeholder there’s the static method Texts.placeholder(...)

I’m using the ResourceBundleTranslation to read text from a ResourceBundle and I’m asking how to get Placeholders or TextColors from them?

You don’t, a Translation object represents a key to substitute values into.

Use Texts.builder(Translation, Object...) to build a text object which contains colors etc
