The image displays two globe artichokes. The top one is exposed to regular daylight and the bottom one is illuminated by a 365 nm ultraviolet (UV-A) blacklight from Kroger supermarket.

Both artichokes appear identical when viewed under regular light conditions. They are green on their exterior, with some of the leaves appearing yellowish in color due to aging. The purple-colored part at the base of the stem and surrounding the white interior is the artichoke's heart.

However, upon exposure to UV-A light, the bottom artichoke exhibits a striking transformation. Its green exterior takes on a more vibrant appearance, while the purple-colored area around its heart becomes even deeper in color. The heart itself also shows increased brightness and vibrancy, now displaying shades of blue and white rather than just purple.

The image suggests that UV-A light can enhance the natural colors present in artichokes, although it does not provide information about whether this effect is solely due to UV-A light or if other factors are involved. – AI vision

El Globo de la alcachofa seccionado cuando se expone a la luz diurna regular, así como cuando es iluminado con una luz negra ultravioleta (UV-A) de 365 nm en el supermercado Kroger. College Station, Texas, 10 de septiembre de 2024. La imagen muestra dos globos de alcachofas. El superior está expuesto a la luz diurna regular y el inferior está iluminado con una luz negra ultravioleta (UV-A) de 365 nm del supermercado Kroger. Ambas alcachofas parecen idénticas cuando se ven en condiciones de luz normal. Tienen un exterior verde, con algunas hojas que aparecen amarillentas debido al envejecimiento. La parte morada en la base del tallo y que rodea el interior blanco es el corazón de la alcachofa. Sin embargo, tras la exposición a la luz UV-A, la alcachofa inferior muestra una sorprendente transformación. Su exterior verde adquiere un aspecto más vibrante, mientras que la zona morada que rodea su corazón se vuelve aún más oscura de color. El propio corazón también muestra aumento de brillo y vibrancia, mostrando ahora tonos azules y blancos en lugar de solo púrpura. La imagen sugiere que la luz UV-A puede potenciar los colores naturales presentes en las alcachofas, aunque no proporciona información sobre si este efecto es únicamente debido a la luz UV-A o si intervienen otros factores. – Spanish translation
