COSLICK COLORS. Jane Coslick’s use of color in her designs is unparalleled and so sought-after that she’s created a line of paints for homeowners who want to mimic her look. When using color in her cottage, she is extremely intuitive. “I use color to create interest, and I’m able to visualize where that needs to be,” she says. For her cottage, she had several cabinets painted different shades of turquoise and teal. She says, “They are all slightly different and work together.”
