Logitech crayon for iPad 9th gen

So basically my apple pencil 1st gen has unfortunately broken and I know at this stage the 9th gen iPad is quite old but I can't afford to replace it right now. Instead I'm thinking of getting the Logitech crayon because if I get the apple pencil 1st gen again when I eventually upgrade my iPad I'd also have to replace that.

So I have two questions: First, on the Logitech website it says that the crayon is compatible 2018 or over iPads but it doesn't say on the apple website that it is compatible with the 9th gen. Is it?

Second, is there a difference between the orange cap crayon and the grey one? Will only one of them be compatible with my iPad?
