A Wordless Book is a Christian evangelistic book. Evidence points to it being invented by the famous London Baptist preacher Charles Haddon Spurgeon, in a message given on January 11, 1866 to several hundred orphans regarding Psalm 51:7 "Wash me, and I shall be whiter than snow." It is called a "book", as it is usually represented with pages, although it can be shown on a single page or banner.
The book consists of several blocks of pure color that, in sequence, represent a nonverbal catechism about basic Christian teachings for the instruction of children, the illiterate, or people of different cultures. However, the presentation of the book is meant to be a verbal experience, providing the "reader" a visual cue to expound Christian doctrine extemporaneously or in impromptu situations.
Variations on a theme 
Spurgeon’s concept only contained three colors: “first was black, the second was red, and the third was pure white”
- Black: representing the sinful state of humanity by nature. Usually referred to as the dark page.
- Red: representing the blood of Jesus.
- White: representing the perfect righteousness which God has given to believers through the atoning sacrifice of Jesus Christ his Son.
Different versions came about when Dwight Lyman Moody added another color: gold (after white) – representing Heaven – in 1875. Hudson Taylor and missionaries of the China Inland Mission used the four color version in open-air preaching and individual evangelism. It has been used by missionaries and teachers such as Jennie Faulding Taylor, Amy Carmichael, Fanny Crosby (who was blind), and modern day Child Evangelism Fellowship which added a fifth color: green (after white, before gold) – representing one's need to grow in Christ after salvation. Some modern Baptists add a sixth color: blue (after white, before green) – representing baptism.
Color cosmology 
The success of the Wordless Book in communicating with East Asian peoples is arguably due to the influence of "color cosmology" (Wu Xing) or color psychology in Chinese culture. For example, in Chinese symbolism, red is the color of good luck and success, and is used for decoration and wedding attire (during the traditional half of the wedding ceremony, while the bridal attire in the modern half is usually white). Money in Chinese societies is traditionally given in red packets; while white is the funeral color instead of black.
Different forms 
Wordless books have been put into many forms for easy use and insertion into everyday situations. Among these are wristbands and various sports gear, including soccer balls, basketballs, and volleyballs.
