I love the light.
I don't agree about your claim regarding the One, though. Numerology is all well and good, but why this particular number?
I see different colours are our perception of life as seen through a lens and interpreted by our mind in our given capacity.
The source of light contains all light wave lengths which are seen as all the colours when refracted through a prisim and then interpreted.
One of the prayers of the Bab talks about this
"O Divine Providence! This assemblage is composed of Thy friends who are attracted to Thy beauty and are set ablaze by the fire of Thy love. Turn these souls into heavenly angels, resuscitate them through the breath of Thy Holy Spirit, grant them eloquent tongues and resolute hearts, bestow upon them heavenly power and merciful susceptibilities, cause them to become the promulgators of the oneness of mankind and the cause of love and concord in the world of humanity, so that the perilous darkness of ignorant prejudice may vanish through the light of the Sun of Truth, this dreary world may become illumined, this material realm may absorb the rays of the world of spirit,
these different colors may merge into one color and the melody of praise may rise to the kingdom of Thy sanctity.
Verily, Thou art the Omnipotent, and the Almighty!"
Baha'u'llah also wrote of the merging of Names into One.
It is indeed a big topic to pull a thought for here and there on, it is man's greatest mystery, the source of creation.
