Is this a croton?

I've been treating it like one but I was unable to find a plant like this either in a nursery or anywhere online. It kinda looks like a curly boy croton but without being curly:

It has yellow specks so I thought "Gold Dust Croton" but all the species I've seen have only green leaves. This one also has deep red leaves where it receives the most sun......

I've rooted it successfully but it bugs me that I don't know for sure what type of plant it is.
