Yellow red may indicate some plane of the overmind.
It is from the overmind that all these different arrangements of the creative Truth of things originate. Out of the overmind they come down to the Intuition and are transmitted from it to Illumined and Higher Mind to be arranged there for our intelligence. But they lose more and more of their power and certitude in the transmission as they come down to the lower levels. What energy of directly perceived Truth they have is lost in the human mind; for to the human intellect they present themselves only as speculative ideas, not as realised Truth, not as direct sight. A dynamic vision coupled with a concrete undeniable experience.
The great Gods belong to the overmind plane, in the supermind they are unified as aspects of the Divine, in the overmind they appear as separate personalities. Any godhead can descend by emanation to the physical plane and associate himself with the evolution of a human being with whose line of manifestation he is in affinity. But these are things which cannot be very easily understood by the mind, because the mind has too rigid an idea of personality - the difficulty only disappears when one enters into a more flexible consciousness above where one is nearer to the experience of One in all and All in one.
