Three Colours: White (French: Trois couleurs : Blanc ) is a 1994 French-Polish comedy-drama film co-written, produced, and directed by Krzysztof Kieślowski.
 "White" is the second in "The Three Colors Trilogy", themed on the French Revolutionary ideals, following "" and preceding "".
 The film was selected as the Polish entry for the Best Foreign Language Film at the 67th Academy Awards, but was not accepted as a nominee.
The Mainz Psalter was the second major book printed with movable type in the West; the first was the Gutenberg Bible.
 It is a psalter commissioned by the Mainz archbishop in 1457.
 The Psalter introduced several innovations: it was the first book to feature a printed date of publication, a printed colophon, two sizes of type, printed decorative initials, and the first to be printed in three colours.
 The colophon also contains the first example of a printer's mark.
 It was the first important publication issued by Johann Fust and Peter Schoeffer following their split from Johannes Gutenberg.
Requiem for my friend is a major and the first non-film musical work composed by Zbigniew Preisner.
 The composition was meant to honour the composer's late friend, the director Krzysztof Kieślowski, with whom he collaborated while working on a number of films, including the famous "Three Colours" trilogy.
 The album was released in 1998 although some parts of the work must have been ready upon Kieślowski's passing as Preisner asserted in an interview that "the Requiem had accompanied Krzysztof in his last journey".
Three Colours: Blue (French: Trois couleurs : Bleu ) is a 1993 French drama film directed and co-written by Polish filmmaker Krzysztof Kieślowski.
 "Blue" is the first of three films that comprise the "Three Colours" trilogy, themed on the French Revolutionary ideals of liberty, equality, and fraternity; it is followed by "" and "".
 According to Kieślowski, the subject of the film is liberty, specifically emotional liberty, rather than its social or political meaning.

The Hokusai Manga (北斎漫画 , "Hokusai's Sketches") is a collection of sketches of various subjects by the Japanese artist Hokusai.
 Subjects of the sketches include landscapes, flora and fauna, everyday life and the supernatural.
 The word "manga" in the title does not refer to the contemporary story-telling "manga", as the sketches in the work are not connected to each other.
 Block-printed in three colours (black, gray and pale flesh), the Manga comprise literally thousands of images in 15 volumes, the first published in 1814, when the artist was 55.
 The final three volumes were published posthumously, two of them assembled by their publisher from previously unpublished material.
 The final volume was made up of previously published works, some not even by Hokusai, and is not considered authentic by art historians.
