What is the ruling on mud and color festivals that involve throwing colors, sliding on mud, covering bodies with it, and include intermingling between the sexes?

It is forbidden for a Muslim to participate in festivals that are religious holidays for disbelievers, because holidays are among the rituals of nations, and revelation has specified the holidays of Muslims and prohibited exceeding them to others. These festivals involve unlawful mixing between women and men, and extravagance in clothing, water, and colors, which is a great evil and an excess in a corrupt matter.
