Hello,
This is a volume candle chart. It consists of green, red, grey and white candles. This is selected on Kite from the Display dropdown > Volume Candle.
Grey candles are formed when the close of the candle is same as the close of the previous candle.
This works differently as opposed to regular candlestick charts which consists of only green and red candles.
Candlestick charts can be selected from Display > Candle(option 1)

An excerpt from the article,
“Volume candle charts have the wicks or tails and filled/unfilled body features of Candlestick charts, as well as the volume-based body width of Equivolume charts. This combination gives us the unique ability to study Candlestick patterns in combination with their volume.”
