A press release from LA 2024 explained the significance of its Olympic symbol, per Zaccardi:
The soaring figure of the logo is a symbol of athletes reaching for their dreams, the original Spanish name for Los Angeles 'the City of Angels," and the Angeleno spirit of optimism and progress that defines Southern California.
The figure is illuminated, lifted and empowered by the rays of the sun, which emanate from a sparkling point of light at the figure's heart — a palette of colors often seen in the city sky both at dawn and sunset.
