How to make the Earth red again?

An alien entity fell in love with Earth a long time ago. When he came back to her, she looked different. He would like to return Earth to her Hadean eon when she was much hotter.

This entity has abilities that are comparable to what we suspect a Kardashev Type 2 civilization would be capable of.

The entity would like to return Earth to the Hadean eon without having to throw tons of rocks at her or changing her composition. And he doesn't want to use a Mega bomb if it isn't necessary. A bomb can be used, but he wants to make sure that Earth doesn't lose too much weight in the process. Any loss bigger than 1% will be noticed.

The time and energy spent to bring her back is irrevelant, but the sooner the better.
