A natural brilliant blue coloring has been discovered by an international team of researchers including chemists at the University of California, Davis. The work is published April 7 in Science Advances. Having the right blue color is also important for mixing other colors, such as green. Red cabbage extracts are widely used as a source of natural food colorings, especially reds and purples. These dyes are called anthocyanins. But the natural blue coloring is present only in tiny amounts.
Why Lightbulb Choices Matter
Light-emitting diode - Wikipedia
Although it is environmentally friendly, blue light can affect your sleep and potentially cause disease. Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in relative darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted. But we may be paying a price for basking in all that light.

The word qualitative implies an emphasis on the qualities of entities and on processes and meanings that are not experimentally examined or measured [if measured at all] in terms of quantity, amount, intensity, or frequency. Qualitative researchers stress the socially constructed nature of reality, the intimate relationship between the researcher and what is studied, and the situational constraints that shape inquiry. Such researchers emphasize the value-laden nature of inquiry. They seek answers to questions that stress how social experience is created and given meaning.
