Despite its name, black holes have no color. This is because color is basically light detected by your eyes. Since light cannot escape from a black hole, it has no color.
However, the rings of matter that have not yet fallen in to the black hole may have a variety of colors.
No, not all black ink pens contain the same shade of black. Different brands and types of pens use varying formulations for their ink, resulting in slight differences in the color of black ink produced.
Black ink may be made in a wide variety of ways, the easiest is simply to use finely divided carbon black particles (e.g. from soot) in which case the only color in the ink is black.
One method to separate dyes of different colors in black ink is through a process called chromatography. In chromatography, the ink sample is placed on a material that allows the dyes to move at different rates, based on their chemical properties. As the dyes separate, they can be visually distinguished by the bands of different colors they produce on the material.
Yes, black ink is generally cheaper than color ink because it is used more frequently in printing. Color ink can be more expensive due to the additional cartridges needed to produce different colors.
When you mix cyan, magenta, and yellow ink together, you get a shade of black. This is because these three colors are the subtractive primary colors and combine to absorb light and create a darker hue.

Black biro ink typically consists of a mixture of black, blue, and purple color pigments. These colors combine to create the dark and rich black color commonly seen in biro pens.

Ink cartridges are the parts of inkjet printers that contain the ink. They place the ink on paper during printing. Ink cartridges are replaceable and sometimes can be refurbished, which decreases cartridge waste and can provide savings. Black ink cartridges only contain a reservoir for black ink while color ink cartridges contain three different reservoirs for cyan (blue), red and yellow. Chips or electronic contacts on ink cartridges allow them to communicate with the printer.

Yellow red and blue
Color printers use all of the colors plus a little black ink to make black. Since the other colors come in smaller cartridges you'll be replacing them more often than the black.
