Dating back to at least the 1940's and the heyday of the Beverly Hills Hotel, pink and green is a very popular color combination. I remember walking through the public spaces when I lived in Los Angeles and being impressed by the tropical murals on the walls in shades of green, and the pink napkins with their distinctive logo on every table.
Other famous pink hotels? The Don Cesar in St. Pete and, of course, The Royal Hawaiian in Honolulu. The lush settings of each hotel provide a green backdrop.
Pink and green is an extremely popular color combination on cakes for girls of all ages. The soft green shades have been traded for a more vibrant lime green, but the combination is still classic.
This three tier cake celebrated a 90th birthday yesterday. One of four cakes created for the party, this was the only one with candles -- each represented five years...
On the other edge of the age spectrum is this shower cake welcoming a baby, and adding chocolate brown as an accent color.
Pink on pink is also trendy. A bold pink is feminine but strong, while the soft pink provides a contrast that gives layers of depth.
Green? Not surprising given the environmental trends many people have today. Especially soft greens that border on yellow.
Another hot color? Olive green -- not to be confused with the avocado green of the 1970s. But that's a subject for another day.
