A personal diary is usually a daily record of what happened over the course of a day while a business diary often records appointments for the future, together with notes of actions to be carried out or objectives to be met. Diaries can be of various sizes, from desk diaries, with A4 or letter size pages for a single day, allowing notes on calls or work to be done, to small pocket diaries holding a week to an open double page, which allows a note simply of appointments to be met in the coming week.
A coloring diary can be either of these or even a journal giving you practice in coloring or helping you meet a daily artistic target. It can be useful to carry a colouring diary with you to make use of spare time traveling (and even help overcome nervousness about traveling). It can hold your appointments and some may include pages for aims and objectives, whether personal or business. Coloring can be a useful distraction if you are trying to solve a problem because it allows your subconscious to carry on trying to find a solution while you color a picture or quote, for instance. A solution, or a means of finding one, can often appear while the mind is distracted by focusing on coloring an intricate picture. If you want to carry a coloring diary with you, it will also be useful to carry a set of pencils or crayons also.
One of the first coloring diaries was created by an Edwardian Lady in England in 1906. She made her own drawings but you can get black and white versions of these for coloring in yourself. Other coloring books are notebooks with some lined pages on which you can make notes, rather than acting as dated entries. You can also get spiral bound notebooks and coloring notebooks that have small coloring areas with a large area for notes.
Coloring diaries are usually personal to the author, though some can be intended for publication, however, these would usually comprise the artist’s own drawings, rather than those purchased from elsewhere.
Some coloring pictures are intended for display, which means that only one picture should be on any one side of a sheet of paper, so that no picture is hidden by another and the colors used will not affect another picture.
