Pirelli is F1’s sole tire supplier and teams are required to use at least two different compounds among the three choices provided at each venue. (Wet conditions modify this; and there are other regs based on qualifying.) Among the seven color-coded dry-weather Pirelli compounds, hyper-soft are identified by pink sidewalls; ultra-soft, by purple. Obviously hypers wear more quickly than ultras.
