This beautiful phrase literally means "blue like the color of the sea" and is the title of this iconic song by Tim Maia.
More than just a color, it represents a feeling of ultimate peace and hope. Tim Maia sings about having "um sonho todo azul, azul da cor do mar" (a dream all blue, blue like the color of the sea) as the reason to live, even when life is hard. It's a perfect example of the poetic, soulful imagery found in classic Brazilian music.
Tim Maia starts this track wishing everyone would just sit down and listen to him: "Se o mundo inteiro me pudesse ouvir / Tenho muito pra contar / Dizer que aprendi" ("If the whole world could hear me / I have so much to tell / Say what I've learned"). What did he figure out? Something pretty blunt and unfair about life. He drops the cold truth that "um nasce pra sofrer / Enquanto o outro ri" ("one is born to suffer / while the other laughs"). Notice how he uses "a gente" here—in everyday Brazilian Portuguese, it literally means "the people," but everyone uses it as an informal way to say "we."
Instead of staying bitter about that inequality, he turns the mood around completely. He insists that anyone going through hard times has to keep searching for "razão para viver" ("a reason to live") and find a purpose to dream. That leads straight into his big, beautiful visual: "Ter um sonho todo azul / Azul da cor do mar" ("To have a dream completely blue / Blue the color of the sea"). English speakers usually associate the word blue with sadness, but Tim flips that on its head. Here, blue is pure peace, vast and calming like open water.
Tim Maia, born Sebastião Rodrigues Maia in Rio de Janeiro in 1942, was the singer who gave Brazil its own brand of soul. He started out as a teenage drummer and singer in the Tijuca neighbourhood, spent a few restless years in the United States soaking up rhythm and blues, then came home and poured all of it into Portuguese.
His self-titled 1970 debut made him a national star almost overnight, carried by classics such as "Azul da Cor do Mar" and "Primavera". Over the next three decades he practically invented samba soul and Brazilian funk, took a famous mystical detour with the "Racional" albums, and became as legendary for his huge, unpredictable personality as for his voice. He died in 1998 at the age of 55, and his songs are still everywhere in Brazil, from beach radios to film soundtracks.
