Close your eyes and call up a place that makes you happy. Take in the sounds, the smells, but most importantly, the colors.
If you’re in your garden, there will be lots of greens: light, dark, edged with red and so on. There might also be an abundance of color if the flowers are in bloom.
If it’s a vegetable garden, there might be things growing. Think oranges, reds, greens.
Perhaps you think of the forest with tall trees looming overhead. Then browns will dominate the scene, with greens overhead.
Your task is to write a scene in which your character is inundated with color. Don’t narrate the scene, but use action and dialogue to make the colors stand out.
Readers will want to experience that place through your characters’ eyes.
Have fun with this one.
