Daffodil in the context of "Tepal"

Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575–585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet).

Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were used to represent gold and skin color in Egyptian tombs, then in the murals in Roman villas. In the early Christian church, yellow was the color associated with the Pope and the golden keys of the Kingdom, but it was also associated with Judas Iscariot and used to mark heretics. In the 20th century, Jews in Nazi-occupied Europe were forced to wear a yellow star. In China, bright yellow was the color of the Middle Kingdom, and could be worn only by the emperor and his household; special guests were welcomed on a yellow carpet.

Carotenoids (/kəˈrɒtɪnɔɪd/) are yellow, orange, and red organic pigments that are produced by plants and algae, as well as several bacteria, archaea, and fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes – xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons and contain no oxygen).

All are derivatives of tetraterpenes, meaning that they are produced from 8 isoprene units and contain 40 carbon atoms. In general, carotenoids absorb wavelengths ranging from 400 to 550 nanometers (violet to green light). This causes the compounds to be deeply colored yellow, orange, or red. Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species, but many plant colors, especially reds and purples, are due to polyphenols.

The culture of Wales encompasses the Welsh language, customs, festivals, music, art, cuisine, mythology, history, and politics. Wales is primarily represented by the symbol of the red Welsh Dragon, but other national emblems include the leek and the daffodil.

Although sharing many customs with the other nations of the United Kingdom, Wales has its own distinct traditions and culture, and from the late 19th century onwards, Wales acquired its popular image as the "land of song", in part due to the Eisteddfod tradition.

Narcissus poeticus, the poet's daffodil, poet's narcissus, nargis, pheasant's eye, findern flower or pinkster lily, was one of the first daffodils to be cultivated, and is frequently identified as the narcissus of ancient times (although Narcissus tazetta and Narcissus jonquilla have also been considered as possibilities). It is also often associated with the Greek legend of Narcissus. It is the type species of the genus Narcissus.

The Isles of Scilly Wildlife Trust, formed in 1985, is a Wildlife Trust covering the Isles of Scilly, a group of islands off the coast of Cornwall. It became the 46th member of The Wildlife Trusts in 2001 and is dedicated to ensuring that the archaeological and historical remains on the islands, as well as the flora and fauna, are protected and maintained. Since September 2021, the Chief Executive of the trust has been Julian Branscombe.

The Isles of Scilly Wildlife Trust, a small, local independent charity, leases all of the uninhabited islands, islets and rocks and much of the formerly "untenanted land" (including almost all the coast) on the inhabited islands from the Duchy of Cornwall for a peppercorn rent of one daffodil per year. As tenants of the Duchy of Cornwall the Isles of Scilly Wildlife Trust has a 99 year fully insuring, repairing lease and is responsible for more than 50% of the Islands. The Trust previously worked in conjunction with the Cornwall Wildlife Trust and jointly produced a thrice yearly magazine called Wild Cornwall & Wild Scilly which ended in the Summer 2014 edition. Members are now sent an e-newsletter.
