There are four colors that can be seen in the eyes of Zeir Anpin. They are White for Chokmah on the Right column. Red for Binah on the Left column. Green for Tiferet on the Center column, and Black for Malchut. They illuminate in the four compartments of the Tefillin that fill the cavities of the brain in the skull. The scrolls inside the Tefillin have the aspect of the brain and the upper three sefirot. The houses of the tefillin have the aspect of the brain cavities and the six sefirot of Z”A.
The Light in the eyes shines the six sefirot of Z”A, and with Malchut, they are called the eyes of YHVH.
The white in the eye is Chessed, the red is Gevurah, green is Tiferet that includes Netzach, Hod, and Yessod. The eyesight comes out of the black of the eye that is Malchut.
“כִּי הִנֵּה הָאֶבֶן אֲשֶׁר נָתַתִּי לִפְנֵי יְהוֹשֻׁעַ עַל אֶבֶן אַחַת שִׁבְעָה עֵינָיִם.”
“For behold, the stone That I have laid before Joshua: Upon the stone are seven eyes.”
The ‘stone’ is Malchut and the seven eyes are the seven aspects of Malchut.
“כִּי מִי בַז לְיוֹם קְטַנּוֹת וְשָׂמְחוּ וְרָאוּ אֶת הָאֶבֶן הַבְּדִיל בְּיַד זְרֻבָּבֶל שִׁבְעָה אֵלֶּה עֵינֵי יְהוָה הֵמָּה מְשׁוֹטְטִים בְּכָל הָאָרֶץ.”
“For who has despised the day of small things? For these seven rejoice to see The plumb line in the hand of Zerubbabel. They are the eyes of YHVH that wander all over the whole earth.”
From the red color in the eyes come out seven other eyes. They oversee judgments because red is the Left column and judgment. They are called ‘the eyes of YHVH’ “wandering all over the land”. The word ‘wandering’ is written in female form, and not ‘wandering’ in a male form because the seven eyes from the red are all judgments.
From the green of the eye, come out seven other eyes, which would reveal the deeds of man, whether good or bad, as it is written Job 34:21 “כִּי עֵינָיו עַל דַּרְכֵי אִישׁ וְכָל צְעָדָיו יִרְאֶה.” “For His eyes are on the ways of man, And He sees all his steps.”
The green is for the center column that includes both Mercy and judgment. From the white color of the eyes come out mercy and all the good in the world to do good for Israel. Then all three colors Red, Green, and Black, bathe in the white that is only mercy to bring mercy upon them.
