Map 810 The Lines of The I Ching in Jin & Jang

Isn't it odd that the Jang lines which are a solid open filled with light, lines which should look the lightest actually look like the darker area of the map shown in miniature below. Clearly it is not the energy in the line we are seeing but what is surrounding it so although the Jin lines are black the light around them is brighter for it.  Strange how things are not always as they seem.

So there is more Jang white solid lines to the bottom and right of the chart and yet the top and left hand side appear brighter.
