I could understand the push for clean hafts back in the 70's and before. Back then, haft marks were almost always a dull shade of brown that muddied up the overall color of the flower. When I was a kid, my mom had the most beautiful light blue TB, but even then I thought it was marred a bit because it had light brownish hash marks.
We are way past that now, though, have been for at least a couple of decades really. I think the markings on your seedling provide some nice pop, diggit.
