That sounds similar to this one http://www.mangago.zone/read-manga/the_justice_of_villainous_woman/
The FL is reincarnated, the other woman is the villain and she asked the prince (the ML) to go to the Crystal Palace. They're both fighting to be the queen.
(My memory is very blurry)
I've been looking for a manhwa where the FL was put in some sort of competition against another woman for the queen's title. I remember that the other woman was a villain and that the FL was reincarnated? I remember one detail about the villain asking the ML about going to the crystal palace or something
The manhwa was in full color
