Not a linguist or Japanese speaker so I am going by Fikira's site. He has Asagi translated as light yellow, mizu which is water gives mizu asagi, blue like water etc. Now this comes probably from google translate and I would be interested if a Japanese speaking person can correlate that. The colors he shows under asagi range from grey to green to yellow. I think that's where the occasional confusion of what's kiita and what's asagi comes from, when you hit the yellow spectrum.
One thing I can add is when I see stones where the yellow meets the grey - I like that a lot.
