Colorspin was a "tall, lengthy"[2] bay mare bred in France by Egon Weinfeld's Hampshire-based Meon Valley Stud.
Like the other horses raced by the Meon Valley Stud, Colorspin competed in the black and white colours of Helena Springfield Ltd a company owned by Weinfeld.
[3] She was trained by Michael Stoute at his Beech Hurst stables in Newmarket, Suffolk, where she was one of an outstanding group of fillies which also included Sonic Lady and Untold.
[2] Colorspin began her second season in the Musidora Stakes (a trial for The Oaks) over ten furlongs at York Racecourse in May and finished third behind Rejuvenate and Ala Mahlik.
On her final appearance Colorspin was matched against male opposition and older horses in the Irish Champion Stakes at Phoenix Park Racecourse on 7 September.
She never looked likely to win and was outpaced in the straight, coming home eleventh of the thirteen runners, some sixteen lengths behind the winner Park Express.
