And with these three colours does a candle shine, which is: (Prov. 20:27) A candle of Y”Y is the soul of adam (human, =45). What is ‘adam’? YOD QE VAV QE (=45).
There are three colours of a candle, and these three colours are the garments of the three Patriarchs, which are white, red and green, the colour black is their ‘darkening’, and of it is stated: (Is. 50:3) I shall dress the heavens with darkness, and in them are enclothed H-V-H. Blue (te-khelet) is the garment of the letter Yod י, which is the essential point (takhlit) of everything.
