Runners in white T-shirts were doused in brightly colored powder — blue and red, yellow and green — as they participated in a colorful race celebrating first-generation immigrants over the weekend.

The 3K race at Mike Ward Community Park in Irvine on Saturday, April 20, was one of the last festivities of the second annual Irvine Tech Week. It was called the FirstGen Color Run to celebrate first-generation immigrants and “people who believe in the American dream,” according to John Shen, founder of Sunstone Management, an Irvine-based private capital firm that invests in early-stage companies.

All proceeds from the race will benefit the Sunstone Community Fund, a charitable organization that provides support to nonprofits, universities and public and private partners that develop entrepreneurship programs and early-stage tech accelerators.
