Unable to change nickname color via run_command

[AE720]

This is a little ambiguous so I wasn't sure if this fell on MiniMessage or not.

The goal is to change the color of the user with a command in a book.

<click:run_command:"/nick &0%player_name%">TEST
To the console is /nick <reset><black>[PlayerName]

It would be really nice if could be omitted in the even of the /nick command and &0 went through.

EDIT: Realizing I was on 1.7.1. It now looks like <!obf><!b><!st><!u><!i> on 1.7,2

Hopefully it's as simple as maybe adding a unique tag that an if/else statement can remove those tags and append what you typed literally in the event there's other use cases without singling out the condition of /nick command being parsed.

After discovering HTML codes will work such as this, the problem took care of itself. You can either close it. Or this can just be a workaround until conditions are cleaned up in the string builder
/nick &#FAD7A0%player_name%
