Egg-colour of the green breed : ordinary brownish slate with various 

 shades of green (Fig. 6), some of them having no green shade. It 

 resembles in colour the Chinese colour but the shades are different, 

 so we are able to distinguish the Chinese colour from that of Japanese 

 green.

Egg colour of " Papillons noirs " : slate grey, more or less shaded 

 with green as in Japanese green ; sometimes without any greenish 

 shade; the general colouration, however, differs from that of the 

 Chinese, Japanese or Theophila green, each of them having its own 

 characteristics: egg-colour of "Tobuhime," normal Japanese colour.
