Rose et vert: Une étude dates from the 1890s, possibly between 1892 and 1899. It is difficult to date, but is dated from the technique and its relationship to other works. 1

Harmony in Blue and Gold: The Little Blue Girl, Freer Gallery of Art

In 1902 the collector Charles Lang Freer (1856-1919) mentioned seeing in Whistler's studio '1 tall lady without background like Little Blue girl', which may have been this study (except that it is not blue). 2 The 'Little Blue girl' was Harmony in Blue and Gold: The Little Blue Girl [YMSM 421], which was painted between 1894 and 1903, and has a similar composition, but with the figure in reverse.
