Joan Miró, Spanish painter, sculptor and cermatitist loved reds, yellows, greens, and blues combined with black and white. Miró insisted that a painting should, "ignite the imagination."
Discovering objects such as spoons and rakes, he created sculptures. He felt anything accidental that occurred in his studio like paint drips or smudges would provide a new work of art.
Writers also can use a sandbox for the subconscious mind. Consider unlikely and unrelated ideas that might collide to create a collage of experience.
Write from a new perspective.
Try a scent, an attitude, and a screech to ignite the imagination.
Add a structure to it.
Find a texture.
Notice what's unlikely.
Add color and write to ignite!
