I did a paper pieced 16" star block quilt with narrow, leftover strips or strips cut as needed from small scraps. I discovered in the process that the less attention I paid to which strip next, the better the finished block looked--and the clashing colors actually added to the overall effect. With the random choice method, the eye isn't directed into any one place, so the overall design once the blocks were sewn together shows as a unit rather than as blocks of color.
