Once you’ve settled on a color, head outside and see where it turns up. You don’t need a picturesque trail or a neighborhood full of flower gardens. Campbell encourages people who think their surroundings are too gray to give it a try anyway: Color can pop out in places you’ve passed countless times without a second glance.

When you find a match, resist the urge to mentally check it off and rush toward the next one, Fisher says. Spend a moment looking at what caught your eye. “The real gift is sitting with it and not just finding it,” she says.

You don’t have to keep your discoveries to yourself, either. “You can do it with a friend, you can do it with your mom,” Campbell says. Searching together gives you something new to talk about.

If you want a souvenir, snap photos along the way. Bernard asked participants in a color walk she led to select their nine favorite images and arrange them into a grid. Together, the collections resembled a patchwork quilt of color. You could make your own collage or save a few pictures to revisit when you need inspiration.
