Blaze Release seems to be Fire mixed with Yin. Considering the Sharingan and MS are supposed to be the Yin half of Hagoromo's power, it wouldn't be far off. That is my theory though.....

Natural Energy is like physical and mental energy. None of these things separately are chakra, they are different forms of energy. Chakra is the result of mixing physical and mental. Adding Natural creates Sage Chakra. The Shinju gathered Natural energy, and the fruit it bore allowed whoever ate it to mix these energies.

Kaguya presumably had 6 Paths Sage Mode, and we learned that chakra passed on to offspring is similar to the parents. While Hagoromo and Hamura got different abilities, they both received 6 Paths Chakra. Hamura got a bit of the short end of the stick for a while because Kaguya's Byakugan hadn't evolved due to its supplementary role, and had to evolve that himself. The Tenseigan seems to grant abilities similar or near identical to the Rinnegan+6PSM.
