The overriding themes of the album were duplicity and opposites – light and dark, night and day, two sides of a coin etc. The artwork needed to tie in with this, so it is primarily monotone throughout. The paint splatter was created during the (extremely messy) making of the band’s music video for the lead single of the album. As such, it was a natural decision that is should be a focus throughout the artwork (art influencing art!).
The sole colour breaking through the monotone is the gold foil of the band name on the cover.
