Close-up of section of globe artichike when exposed to ...

The image presents a striking comparison between two close-up photographs of the same section of globe artichoke, showcasing its appearance under regular daylight and when illuminated by a 365 nm ultraviolet (UV-A) blacklight from Kroger supermarket.

**Image Details**

* The left photograph depicts the artichoke in natural light, with a yellowish-green coloration.
* The right photograph shows the same section of artichoke exposed to UV-A light from a blacklight, resulting in a dramatic change in appearance.
   + The purple parts of the artichoke are highlighted and more vibrant than under regular daylight.
   + The white or pale green areas appear slightly darker.

**Comparison**

* A notable difference between the two images is the increased visibility of purple hues on the right photograph compared to the left one.
* This suggests that UV-A light can enhance the visibility of certain colors in the artichoke, possibly due to its ability to penetrate deeper into the plant's tissues and highlight specific pigments.

**Overall**

The image highlights the unique effects of UV-A light on the appearance of a globe artichoke. The increased visibility of purple hues and darker white or pale green areas suggest that this type of lighting can be useful for observing subtle color differences in plants. – AI vision
