Black is, of course, the darkest color in the Bible. It lacks brightness or a hue, and although it absorbs light, it does not reflect any back. Scripture states that God is light (Psalm 104:2, 1John 1:5) and that Lucifer's name, given him by his Creator, means "light bringer" or "morning star" (Strong's #H1966 in Isaiah 14:12). The universe was initially created not to be dark or black but rather to be filled with light (both literally and figuratively, see Revelation 21:23 - 24, 22:5).
When Lucifer chose to sin, however, he turned the light within himself to black (which God determined beforehand would be a consequence of disobedience - see Isaiah 45:7). He became the first dark 'thing' that had ever existed (John 8:44) when he committed spiritual suicide.
In the physical universe, a black hole is a celestial object whose massive gravity pulls in all matter, including light, yet itself remains dark. Lucifer became a spiritual version of this physical phenomenon when he took all the light God gave him and turning it into darkness.
In Western cultures darkness symbolizes death and mourning. People sometimes wear dark clothes when they are mourning the death of someone they love.
