blue of Lupinus. Further, my dark-blue form is much darker than 
the pure blue in Lupinus. As in Lupinus no trace of violet is seen 
in the blue colour of the Aquilegia flower. 
The white type shows a similar peculiarity as that of Lupinus. 
The white flowers have also here a faint »ghoast-colour», especially 
to be seen in the tip of the spur; but it is much less distinct in 
Aquilegia, however.
