As a physicist, I am often in danger of doing this:

So: it seems like one of the more obvious faults of pylons is that they are the wrong color. Usually, they are white or grey (etc) which does not really gel with the existing natural landscape. It seems like the first step in fixing the problem would simply be to paint them brown, tan, green or blue, depending on the location -- possibly with a few brightly colored details so that they aren't too subtle. Bonus points for a paint that has inherent color variations, because flat colors are too visually distracting. (Why does pylon design even need a journal, anyway?)

Some are indeed painted, but that adds to the cost.

Weathering steel seems like it could be a decent compromise between color and cost. Though admittedly I’m just assuming it would be less expensive than painting and maintaining said paint.
