Black light color converter11/20/2023 This game is majorly about communicating with a satelite a cycle of it sending you puzzles, and you completing and sending them back, so that it can send you more, and so on. The formula below converts CIE 1931 xy values into its Duv value. In this case, the alternate color is actually complementary to the secondary color, so it serves as a nice anchor for balancing the overall hue of the app. A 20 lighter version of the original color is 79FFC2, and 009859 is the 20 darker color. A complement of this color would be D03478, and the grayscale version is 9A9A9A. The color can be described as middle muted spring green. ![]() (Waveform Lighting's FilmGrade series of products have a Duv tolerance of +/- 0.003). Details The Hex color 34D08C is a dark color, and the websafe version is hex 00CC99. For more demanding applications, a Duv range between -0.003 and +0.003 is preferred. In a RGB color space, hex 000000 (also known as Black) is composed of 0 red, 0 green and 0 blue. What are acceptable Duv values?ĪNSI and EnergyStar recommend Duv values between -0.006 and +0.006. If and only if both Duv and CCT values are provided, an exact color point can be pinpointed. On the other hand, if we were given information that a lamp had a CCT value of 3500K and a Duv = 0.001, this would give us sufficient information to know that it is along the 3500K iso-CCT line, slightly above the black body curve. In other words, if a lamp has a CCT value of 3500K, in reality, it can be anywhere along this iso-CCT line. Iso-CCT lines describe points whose CCT value are the same.įor 3500K, you will see the line extend from a yellowish hue in the area above the black body curve (larger Duv value), while it will transition towards a pink/magenta hue as you move down the same 3500K iso-CCT line below the black body curve (lower, negative Duv value). In the graphic below, you will find iso-CCT lines for various CCT values. This is because CCT alone does provide enough information about the exact color. ![]() (d) Measured emission spectrum of down-converted green light with and without the CLC film (filtered. Why is Duv important?ĭuv is an important metric whenever discussing color sensitive lighting applications, such as film & photography. Inset: CsPbBr3 perovskite film under 365 nm UV light. In short, Duv conveniently provides both magnitude and directional information about a color point's distance from the black body curve. It is typically used in conjunction with a correlated color temperature (CCT) value in explaining how close to the black body curve ("pure white") a particular light source is.Ī negative value indicates that the color point is below the black body curve (magenta or pink) and a positive value indicates a point above the black body curve (green or yellow).Ī more positive value indicates a point farther above the black body curve, while a more negative value indicates a point farther below the black body curve. Duv is a metric that is short for "Delta u,v" (not to be confused with Delta u',v') and describes the distance of a light color point from the black body curve.
