NEW YORK—If fall's gray palette seems a bit depressing, get ready for a dose of fashion Prozac.

The spring collections shown at New York Fashion Week were full of optimism, featuring bright colors and bursts of gold. Donna Karan showed a graffiti print in hot pink for her DKNY line on Sunday, while Michael Kors took on a disco theme.

Throughout the week, there's been hardly a hint of black, if you ignore the audience.

Kors' collection featured sunny gold, as did those of Proenza Schouler and Ralph Lauren—the toast of one of the week's highlights, his 40th anniversary celebration on Saturday.

And if there wasn't enough celebrity-spotting at that black-tie event or in the runway's ront rows, Sunday marked the debut of Nicky Hilton's line, Nicholai. Sister Paris was notably absent.
