The Golden Ratio is a mathematical ratio often found in nature, art, and design. It gives the world around us composition and symmetry that, for reasons we don’t fully understand, we find beautiful. It appears in the spiral of a seashell, the uncurling of a fern, and many other natural structures. When applied to the arts, it becomes a tool for creating balanced, organic works.
Each pencil contains Blackwing's balanced graphite and features a design inspired by the Fibonacci sequence, a series of numbers that approximate the Golden Ratio. The width of each color block is the sum of the widths of the previous two color blocks (1, 1, 2, 3, 5, 8, 13, 21, 34, & 55mm). A simple formula with a magnificent result.
