Editing Aconitum (section)

===Color range===
A medium to dark semi-saturated blue-purple is the typical flower color for ''Aconitum'' species. ''Aconitum'' species tend to be variable enough in form and color in the wild to cause debate and confusion among experts when it comes to species classification boundaries. The overall color range of the genus is rather limited, although the palette has been extended a small amount with hybridization. In the wild, some ''Aconitum'' blue-purple shades can be very dark. In cultivation the shades do not reach this level of depth.

Aside from blue-purple—white, very pale greenish-white, creamy white, and pale greenish-yellow are also somewhat common in nature. Wine red (or red-purple) occurs in a hybrid of the climber ''Aconitum hemsleyanum''. There is a pale semi-saturated pink produced by cultivation as well as bicolor hybrids (e.g. white centers with blue-purple edges). Purplish shades range from very dark blue-purple to a very pale lavender that is quite greyish. The latter occurs in the "Stainless Steel" hybrid.

Neutral blue (rather than purplish or greenish), greenish-blue, and intense blues, available in some related ''[[Delphinium]]'' plants—particularly ''[[Delphinium grandiflorum]]''—do not occur in this genus. ''Aconitum'' plants that have purplish-blue flowers are often inaccurately referred to as having blue flowers, even though the purple tone dominates. If there are species with true (neutral) blue or greenish-blue flowers they are rare and do not occur in cultivation. Also unlike the genus ''Delphinium'', there are no bright red nor intense pink ''Aconitum'' flowers, as none known are pollinated by [[hummingbirds]]. There are no orange-flowered varieties nor any that are green. ''Aconitum'' is typically more intense in color than ''Helleborus'' but less intense than ''Delphinium''. There are no blackish flowers in ''Aconitum'', unlike with ''Helleborus''.
