According to the experiment conducted by Charles and Francis Darwin, blue light induced the most curvature in the coleoptile of oat seedlings. They observed that the curvature response was higher when the seedlings were exposed to blue light than when exposed to other colors of visible light. Therefore, blue light is the most effective color in inducing coleoptile curvature.
