I have a theory that associations between the sub-colors relatively vary in strength/size directly in proportion to the main color.
Thus, red/sub-red is easier to feel because it is stronger in nature, all things being equal, than red/sub-violet.
This would also account for why many systems list 21 secondary chakras and many tertiary ones. I theorize that these secondary and tertiary ones comprise of the 49 sub-colors, but 21 are considered secondary because they are the relatively speaking sub-colors that are larger and most closely related to the primary color.
For example, I have noticed three strong green sub-centers: the actual heart, opposite to the actual heart where basically only the lung is, and the thymus. Under this theory, I should most easily feel, barring any large distortions, green/sub-green, green/sub-yellow, and green/sub-blue.
My experiences with the actual heart seem to correspond with green/sub-green in terms of belief. My experiences with the thymus seem to correspond to green/sub-blue (love and acceptance of communication and guidance or something along those lines). I have not had many experiences with the other area, but my yellow is weaker and under this theory it would be the green/sub-yellow, so perhaps that is consistent with this theory.
