Egyptian blue, also known as calcium copper silicate (CaCuSi4O10 or CaOCuO(SiO2)4 (calcium copper tetrasilicate)) or cuprorivaite, is a pigment used in ancient Egypt for thousands of years. It is considered to be the first synthetic pigment. It was known to the Romans by the name caeruleum – see also the English word cerulean. After the Roman era, Egyptian blue fell from use and the manner of its creation was forgotten.

Different crowns represent the life of the pharaoh and the last crown or Nemes headdress marks the conclusion of earthly life and the beginning of life hereafter.
The Nemes headdress or royal blue striped headdress isn't a real crown but a cloth that often covered a crown and the backside of the head. Two parts of the cloth hung downwards alongside the ears on the front side of the shoulders and on the backside the cloth was tied together in a braid and provided with rings.
The Nemes headdress of the death mask shows the combination of gold and lapis lazuli as well as the contrast and agreement between life (gold-sun-life) and death (heavenly stone lapis lazuli).

The nemyss is the ritual Egyptian head-dress of the pharaohs. It is best known from popular images of the sarcophagus of King Tutankhamen. The nemyss is a folded linen cloth that rises from the brow and hangs toward the shoulders. The nemyss is still in wide use today by Kemetic practitioners and a number of magickal orders, including various Golden Dawn reconstructions and in Thelemic rituals.
So criticism of Wolf Blitzer is antisemitism.
Another anon said the striped door reminded him of Egypt.
I couldn't find more connection than the striped nemes headdress,
and Egyptians liked Lapis Lazuli and developed the blue pigment which looks like it.

Fez Hat History
The city of Fez, in ancient Morocco, is believed by many to be the origin of the fez hat. When the Hajj pilgrimage was temporarily suspended in 980 AD, pilgrims living to the western side of the Nile river were directed to Fez as an effective alternative to the holy city Mecca. Here, a Moor merchant started the supplies of a new style of headdress, which quickly became popular due to the heavy influx of pilgrims in the city. Fez initially had a monopoly on the manufacture of fezzes, because the berry used to color the hats was planted only there.
With time, this style lost its appeal, and was found only with a few people. However, interest in the hat was reignited in 1826, when Sultan Mahmud II of the Ottoman Empire was looking to change the traditional garb of his civil officers into something new. Initially, he thought of using a triangular hat of European descent. However, his advisors pointed out to the three corners represented the Holy Trinity of the Christians, which could sow discord amongst his largely Muslim subjects. So, when a shipment of fezzes arrived from Tunisia, they were selected instead. The hat was publicized as being a badge of identification for Turkish subjects, and even those citizens who were not Muslims were obliged to wear them. Smaller fezzes without tassels were made even for the women. Although it took a while for this fashion to catch on, by the 1900s, the fez had become extremely popular, and was considered to be the national headdress of Turkey.
At one time, the fez was even a symbol of protest against the French occupation of Morocco. However, the legend of the origin has been disputed by other theories, which state that the fez originated in ancient Greece or from the Balkans, but not in Morocco. With the discovery of synthetic dyes in the 19th century, the headdress started being manufactured across Europe. By the beginning of the 20th century, Austria had become the new capital of the fez manufacturing industry.
The fez again came up against a wall in 1925, when the new leader of Turkey, Kemal Ataturk, felt that it was a sign of being backward. He felt that traditional garments should be replaced by British suits and styles. To push Turkey towards alleged modernization, the fez was banned. However, this ban was not taken well by the people of the country, leading to several riots, and large numbers of fezzes being confiscated as illegal contraband. When an attempt was made to overthrow Ataturk, and bring back the fez, 9 - 10 people were shot and killed, virtually making the fez disappear.
