I don't believe this relates just to reggae, this gives a laid back, cruizy feel you're after. Is island records use to have an island icon years ago and they released all types of music and they were a big label. This is more of a unique take on the relaxed island feel.
I kept the colours simple, if you have any colours you would prefer let me know. Rainbow colour scheme's are very reggae as they are the colours of the Rastafarians.
