On the top right of the umbrella, there are some that are at and angle. Compare the dark lines of the blade to the dark lines of the umbrella. What is most obvious is the slanting top right lines that lines up perfectly on the gold and steel areas.

The camera collects data, that is light reflecting off the surface of the katars blade. My theory: In this example, there are slight variences in the wootz surface height from etching. And that when reflected off the gold surface, then give darker and lighter shades of gold, because of varying angled degrees of light bouncing back to the camera .

If this is true, it adds another dimension to wootz steel. This is where an opinion from a metallurgist that has study'd wootz would help.

Great explanation Rand!

My metallurgy compehrension is about at 'Sesame street' level, so thank you for the excellent description of both the photographic and metallurgic factors.
