I also sense a reddish feeling, like the Muladhara (base chakra). However, it's not a pure red, but rather a reddish-brown, and it's not overwhelmingly dark, so in that sense, it's pure, but fundamentally it's the color of the Muladhara.
On Earth, there are evil, conflicting, and demonic entities, and their auras are intensely black. However, the Earth's aura doesn't have that intense blackness. So, the Earth's aura is fundamentally like the Muladhara, but it doesn't seem to contain anything evil.
When I say desert, it may cause a misunderstanding, but it is closer to Sedona. There is a part that feels like a desolate desert, but what is dominant is a warm, enveloping aura of reddish-brown.
This energy radiates from the Earth to the universe, and the universe has a more pure and transparent aura, but from within the Earth, the Earth's aura extends to the surface of the Earth, so the universe cannot be directly felt. However, when you are conscious of the universe, you can see that the universe has a transparent aura.
The Earth's side is based on a powerful reddish-brown energy, which is somewhat desolate, but even though it is said to be desolate, it is full of energy, so it is not destructive, and it is not so creative either. It feels like a desert where high-concentration energy is constantly changing, like it is fluctuating.
In addition to that, there is sadness, and it is understood that sadness is also included in the high-positive, high-concentration reddish-brown energy.
I remember reading somewhere that, according to the American Indian tradition, the Earth's consciousness is like that of a 6-year-old child, and that story resonates with me.
