We all know that when you make a shop you need to advertise it...Well im a little confused, how do the rookies get blue color chat to advertise there shops, is it a command..somebody tell me how!!
They have an item that is named there shop. For instance, if an item says /p h CHEAP, then they simply type [Item] while holding that item in chat, and that becomes blue in chat. Same thing goes for any item. It’s a way people show there enchants on a book or what level there Upgradable Pickaxe is. I am not 100% sure that is how people do it, all I know is that an item is involved with it. Have a nice day!
If you're talking about colour coded chat messages you need be Diamond Rank to send colour coded messages in chat and Coal Rank to use colour coded signs. So as a rookie you can't send colour coded messages in the chat. But as TorontoCanada said you can do "[item]" in your chat message while holding that item to make the item blue in chat and for other users to hover of the item to see the info of the item. I hope this info helps you have a nice day!
Anyone can do [item] but the rookies and ranks below diamond just use it to make their messages stand out more since they can't have color chat like higher ranks do.
All you need to do it is to rename a item as a advertisement slogan, then you just type [item] into chat while holding said item which will display the ad into chat
