Leafspot and melting out lesions on leaf blades first appear as what color?

Explanation:
Purple is the first color you’ll notice with leaf spot and melting out lesions on leaf blades. Early fungal infections often produce purplish or reddish-purple spots as they establish on the leaf surface and tissues respond. As the disease progresses, the center of the lesion can lighten to yellow or tan and the affected tissue may melt away, creating the patchy dead areas described by melting out. Yellow, white, or black can appear later or with different problems, but the initial sign here is the purple coloration.
