Cool black screens blue7/30/2023 We know ultraviolet (UV) is damaging and the blue range is closest to it. “We are seeing a much greater number of age-related macular degeneration patients, even back correcting for the aging population, so the risk factors are clearly changing,” explains Professor John Marshall, Frost Professor of Ophthalmology at the Institute of Ophthalmology in London, “If you look at cataracts there’s a very good correlation between the age of onset of cataracts and the degree of ultraviolet where you live in the world, that’s why people close to the equator tend to get their cataracts 5 to 10 years earlier.” Over exposure could be playing a role in the rise of cataracts and even blindness. There are also some scientists linking blue light to age-related macular degeneration, though the evidence doesn’t seem to be conclusive. Lack of sleep has also been linked with mood problems, anxiety and depression, and increased risk of accidents. Those examples are mostly related to long term night shift, or severe sleep disorders, but any disruption to your circadian rhythm can cause problems. When our circadian rhythms are thrown off researchers believe we are put at more risk of all sorts of things including heart attacks, obesity and type-2 diabetes, and various cancers. There are more serious health issues to consider if you aren’t getting enough sleep. Unsurprisingly, the ebook reader group reported feeling less tired in the evening, but they also reported that they felt more tired in the morning, despite having the same duration of sleep as the other group. On average, they took 10 minutes longer to fall asleep and displayed significantly less rapid eye movement (REM) sleep than the group reading printed books. The patients using the ebook reader showed suppressed levels of melatonin. The paper assessed two groups half read a normal printed book for four hours before bedtime for five consecutive nights, while the other group read a light-emitting ebook reader for the same period. “In the past 50 years, there has been a decline in average sleep duration and quality, with adverse consequences on general health,” so begins an illuminating paper entitled, Evening use of light-emitting eReaders negatively affects sleep, circadian timing, and next-morning alertness, based on research from Harvard Medical School, amongst other places. Our random color generator will output the randomly chosen color in all three systems, for your convenience.“In the past 50 years, there has been a decline in average sleep duration and quality.” Roughly speaking, hue refers to the part of the light spectrum (0-360°), saturation to its intensity (0-1, 0-100%), and lightness to its brightness (0-1, 0-100%). HSL stands for "Hue, Saturation, Lightness" which is an alternative way of encoding colors.A color written in RGB consists of three numbers, each signifying the amount of red, green and blue light that needs to be mixed in to produce the desired end color. RGB stands for "Red, Green, Blue" and mostly applies to digital displays, computer monitors, television screens and so on.For example, the HEX code for the color black is #000000 while the HEX code for a color in the purple range is #8f0f8d. HEX is just a group of six hexadecimal digits and is a representation often used in web design.Three of these are supported in our random color picker: These are various systems for presenting colors in a technical and uniquely identifiable way. The maximum supported number of unique colors is twelve, regardless from which palette they are being picked. Ideally, use a palette with as many colors as the number of unique ones that you need, or slightly more. Additionally you can use the 3-color wheel consisting of the three primary colors ( red, yellow, blue), the 6-color wheel which has the three secondary colors ( orange, green, violet) on top of these, or the 12-color wheel which contains the six tertiary ones in addition to the primary and secondary ones. The color generator supports randomly choosing between red and blue, red and black, and black and white. for players in a game, first input the number of players in the first field, then select an appropriate color palette. If using the random color wheel to generate distinct unique colors i.e. For example, to pick two random colors, enter "2". If you want to pick more than one colour simply enter the number required in the first field. The output is the color, visualized, and its unique code in HEX, RGB and HSL. Our software uses a strong random number generator to produce the values of red, green, and blue that comprise each color. Press the "Pick a Random Color" button if you want the random color generator to produce another color for you. To randomly generate a color simply load this page.
