Marmol Azul means "blue marble" in English. not the round kids toy, but marble like a slab of marble (the stone). When the first astronauts landed on the moon, they looked back at the earth and said it looked like "Blue Marble".

Blues and greens and black for color palette, preferably. but i'll leave that to your expertise.
