First released as Romain BP (2007, three Headline and two Text weights, plus italics) and SangBleu BP (2008, two weights, Hairline and Light, plus italics). The latter was renamed to SangBleu Serif in 2015. An updated version that merges them into a coherent family (minus Romain’s Text styles) was released in 2019, now named SangBleu OG Serif.
Not to be confused with the new SangBleu series (2017), see especially SangBleu Kingdom and SangBleu Versailles.
