The Storm have pretty unique colours in Australia (outside of WA), plus purple and navy perfectly represent a stormy sky. I switched out the yellow for silver to further add to the gloom.
The primary and secondary are based on their set used from 2003-2009 with more purple. The lightning bolts that have been on their jerseys for over 10 years have been simplified since the logos cover up the centre part of the bolt, making a mess. The throwbacks are based on their inaugural uniforms of 1998.
