The color pink has always been a predilection for girls, both girls, including adolescents and adult women. This color seems to be linked to females from long ago, God knows it, since there is no other explanation than a taste transmission from generation to generation.
When we speak of pink should not necessarily be a completely pink room but can be based on color, with subtle details that give an impression to those coming to the predominant color or combination is responsible for space, that is.
But often it is misinterpreted by a pink little girl's room, childish, far from what one can even imagine to have as an adult. But not necessarily so, and without many more words will show some pink bedroom to appreciate beyond childhood trends.
