The idea was simple—render the words ‘Gorgeous Colours’ using bright, vibrant colours. Although each letter used a different colour, they couldn’t differ too greatly from one to the next. By splitting the words up, legibility was already compromised. Had each letter been vastly different in colour to the next, it would have made the band name almost illegible.
Splitting the words up meant the band name could be increased in size and have greater overall impact.
