The vibrancy and duration of colour are quality control parameters ICON takes seriously. This is evident in the performance of Umbrella shells. Belonging to the 'dahlia' family of shells, Umbrella shells are so named because the performance of the pressed comet stars forms a colourful looping canopy resembling a beach umbrella. Umbrella shells can accompany other low level ICON effects such a comets and crossettes because ICON's colour palette consistently extends across their whole product range.
