Abdu'l-Baha about color

"Today I am most happy, for I see here a gathering of the servants of God. I see the white and colored people together. In the estimation of God there is no distinction of color; all are one in the color and beauty of servitude to him. Color is not important; the heart is all-important. It matters not what the exterior may be if the heart be pure and white within. God does not behold differences of hue and complexion; He looks at the hearts. He whose morals and virtues are praiseworthy is preferred in the presence of God; he who is devoted to the Kingdom is most beloved. In the realm of genesis and creation the question of color is of least importance."
