The animation uses a "hot metal" colour scale that begins at dark red and progresses through orange and yellow to white at the highest levels of activity.

影片里用色线标出了活动等级：由深红开始，逐步过渡桔红，再到黄色，进而显成白色这一最高等级。

This should produce a red colour if the metal contains any nickel.

While the materials and construction methods are similar to standard pylons, one point of departure is the colour - white instead of gun-metal grey.

BBC: Could pylons ever be pretty?

The metal's matt sheen generates reflections of infinite variety and colour that shift minute by minute, from silvery grey to a soft pale gold.
