Naarden turns BLUE – An ode to a timeless color
This year, Naarden the Art Fair embraces the color that has inspired artists for centuries: BLUELike a thread running through art history, blue keeps recurring – versatile, recognizable, mysterious. From the iconic Delft Blue that made Dutch art famous far beyond the country's borders, to the deep blue hues of Monet's water lilies and Matisse's expressive nudes. In paintings, a blue sky sometimes betrays the country of origin, while glass artists, jewelers, and even watchmakers have been enchanted by this color for generations. Think of the rich luster of sapphires, the blue dials of nautical timepieces, or the eyes looking at you from a portrait. Blue is everywhere – in seascapes, skies, flowers, glass, and stone – and that is precisely why it is the perfect inspiration for this edition. The theme invites visitors and exhibitors alike to look in a new way. Expect surprising presentations in which blue takes center stage – powerful, poetic, refreshing.
The Waterline Path runs around the fortress, making the scale of the fortifications clearly visible. The fortress also hosts the biennial national Naarden Photo Festival. The entire fortress was owned by the State until January 15, 2016; following the discontinuation of its military function, parts of it were successively transferred from Defence to the portfolio of the Government Buildings Agency, and subsequently transferred by the Government Buildings Agency to the National Monuments Organisation on January 15, 2016. The fortress is a protected cityscape.

International Klein Blue (IKB)

Adam and Klein experimented with the ultramarine pigment and a special fixative, polyvinyl acetate, then known as Rhodopas. Unlike ordinary fixatives, this did not detract from the luster (depth) of the color. Unlike conventional blue paint, in which the fixative—the medium trapping the colored particles—creates a reflection that diminishes the effect, which is stronger (less glossy) with ground pigment, IKB appears grainy or fuzzy to the human eye, particularly on three-dimensional objects. There is absolutely no reflection or gloss. As a result, objects painted with IKB appear powdered or very finely sintered.
Although an internationally recognized patent was never applied for International Klein Blue, Klein did apply for a Soleau envelope at the INPI. This envelope serves as proof of an invention in France. It is solely to record the date of an invention or idea and therefore does not function like a patent.
TriviaFor the Eurovision Song Contest 2024 in Malmö, the Netherlands is represented by Joost Klein with the song Europapa. IKB was the color of the suit that singer Joost Klein wore during his performance at the festival. Joost Klein (1997), known simply as Joost, is a Dutch musician, writer, and former YouTuber. He is known for songs such as Scandinavian Boy, Wachtmuziek, Ome Robert, and Friesenjung, and the albums M van Marketing, Albino, and 1983.

The Scene – Blue (1991)
Blauw is a song by the Dutch rock band The Scene, taken from the album of the same name released in 1991. The song was released as a single on April 8, 1991. It is the title track of the album Blauw, recorded at the Wisseloord Studios in Hilversum and released on October 1, 1990. The single was released by Phonogram on April 8, 1991, and was a regular part of the band's live sets. The song was written by Thé Lau, and the lyrics were inspired by a visit to a Greek restaurant, where Lau noticed how often the color blue is used.
Blauw was mixed in the Wisseloord Studios, among other locations. The B-side, Opgejaagd, was written for Thé Lau in collaboration with keyboardist Otto Cooymans. The single was the band's first commercial success. In the Netherlands, Blauw was the 377th Special Offer on KRO Radio 3 on Sunday, May 19, 1991, and became a radio hit on the two national charts of the time on the national public pop station: the record reached position 14 in the Dutch Top 40 and remained charted for 7 weeks; in the National Top 100, it reached position 15 and remained charted for 11 weeks.

Blue Monday (Monday, January 19, 2026)


The message also received much criticism regarding its content. For instance, there is no explanation whatsoever for how the formula was constructed, and the formula does not measure in the quantity 'time'. Casper Albers, professor of statistics at the University of Groningen, called the formula in 2020 just as nonsensical as a formula like 'three times Wednesday divided by endive'. It is pseudoscientific. Arnall claimed afterwards that he does not regret devising it, but it was supposedly his intention to get people thinking about happiness. Winter depression exists, but it is a long-term condition that can be clinically demonstrated, and not a one-day phenomenon as Blue Monday suggests it is.

As a severely disabled contributor to postzeglblog (fell off my bike due to ice on the road: a new hip joint has made me somewhat mobile again), there is quite a bit of relevant philatelic background information to report regarding the blue on blue stamps.
Perhaps there is a reader who possesses structured information with images and would be willing to share it with interested parties.
Hang in there, Bate, and I hope you're back on your feet soon.
Warm regards from Willem
