The traditional home colours of St Mirren are black and white stripes, however for the first season the colours were scarlet and blue. There is some dispute as to why the colours black and white were chosen. A popular theory is that the stripes represent the Black and White Cart rivers which run through Paisley. In recent years there has been evidence unearthed that the Monks in the local abbey wore black and white striped habits. The team strips have varied very little in the long history of the club, however the thickness of the stripes have often varied. Some years have seen horizontal stripes used.
