When I first activated my byakugan, I saw that the chakra in my body had three distinct colors:brown,blue and purple, or at least I thought that I had only three basic natures .
You see, at first it was just a little gray hue appearing near my brown chakra, it wasn't significant enough for me to think about.But then,around 5 months off training my earth nature, the gray hue was becoming a bit more visible but it was only after I trained my lighting nature and water nature to a certain degree that gray chakra started to appear often at the the three chakra's point of contact.
After observing for a while with my byakugan,I noticed that the gray chakra only emerges when my three chakra natures blend in a certain ratio. Upon further observation,I've concluded that this ratio is roughly 7 parts earth, 2 parts water and 1 part lighting.
Due to being identify the fought ratio, I was able to successfully combine chakra in my body to create this gray chakra.It did take a lot of focusing to get the ratio right at first, after trying for a month , I was able to get the ratio down without much thought and consistency create this gray chakra.
Though I have a few guesses from what it might be, as of yet, I haven't had any solid indication.Other than me,no one is aware of this chakra in my body yet, I can't just tell them can't I?
After a while of pondering, I decided to do something rash, a little experiment to determine what it is once and for all!Although this might backfire on me,I'm sure it's a risk that's worth taking!
Using the hand seals from rock throw jutsu, instead of the usual earth nature chakra ,I used the mysterious gray chakra to mold the same way I do with earth chakra and shoot it out as fast as I could.The gray chakra was very stiff even when compared with earth chakra,yet somehow,from a 5 year old child's pure excitement and enthusiasm alone, I was able to form a relatively small clump of gray chakra and shot it out with all my might.
From the palm of my hands that were opening wide , something small and shiny shot out at high speed and crashed against a boulder creating a sharp metallic sound.

After he heard the high pitched noise,Kuki quickly ran toward the direction that the object flew to,only to discover a boulder with a small crack and below it was a piece of metal,even with its rough surface,Kuki could see his own reflection from it, displaying his face with a stupid looking grin.
Looking at the piece of metal on the ground,Kuki,who was still grinning,stood in silence and complete stillness,as if he was a computer trying to download a huge file,he was truly speechless.
"Is this a metal?!?!"breaking his self created silence,he gasped in a high pitch benefiting an average five year old.
"If my knowledge of knife making material serves me right then…..isn't this…STEEL!?"Kuki spoke to himself with a proud and surprised tone.
"Holy shit! I-I… have a Kekkei Tota!"Kuki slowly said with a gleam and a hint,a small small hint of smugness.
