[4] The album was recorded in Itaipava, a neighborhood of Petrópolis, a city in the mountainous regions of the state of Rio de Janeiro by Brazilian Eng.

It's a three-letter word meant to allude to the fact that Cor is their third album of original songs and that the group involves three people (Caetano, Vitória Falcão and manager Felipe Simas).

[2] The second track, "Te Amar É Massa Demais", has elements of samba-reggae[1] and Mauro Ferreira from G1 considered "Explodir" the "romantic pop fofolk[a] typical of the band".

He noted that the album is "too long for the 2020s phonographic standards", but praised the fact that the duo did not release it "sliced" in EPs or singles, as he states it has become "usual in the market".

He finished his review saying that Cor "exposes Ana Caetano and Vitória Falcão still stuck to a past that brought them premature glory" and that "it's hard not to allow oneself to be enslaved by success".
