Artemis is the virgin goddess of the hunt, chastity, and a protector to young women which makes her a massive feminist. Her whole body and clothes (she typically wears a dress) glow a light blue color. 
Athena is the virgin goddess of war and wisdom. Her body and armor (which she typically wears) glows a silvery grey color, similar to that of metal. Athena also typically wears her helmet just above her face in her hair. 
Both goddesses are just a mood when it comes to relationships and love.
