Black is one of the most beautiful of colors and yet is the void of color too. It is the color of detail.

Black personalities want every thing done in detail. They are statistical and make good accountants.  Internal Revenue Service agents probably like this color.

If a job needs finishing, these are the people to finish it.

These personalities need leaders, though, to tell them what needs to be done.  Under guidance, they are able to get to the crux of the matter and solve very large problems.

When put in a place to find the mistakes of others, they are right at home.  Loving puzzles, and finding others' mistakes brings out their tenacious spirits.  Black personalities will sometimes intentionally find mistakes just so that they can repair them.

This color is one of holding things inside.  When one wears black, they do not want to be touched.  Putting a barrier between themselves and others is the purpose of this color.

Keeping their strength inside so that they can better protect their emotions is the effectiveness of this color. Although they want to be part of the world around them, they want no one to tug at their sensitivity.

Black is a relief color for most people, like "Mom's apple pie". It makes them feel comfortable and even, in some cases, makes them feel smaller, allowing them to hide from the sometimes cruel world.
