However, the RGB color model is device dependent, which means different devices can display a given RGB value differently. W3Schools offers free online tutorials, references and exercises in all the major languages of the web. The optical spectrum of the input and converted signals in those particular. Over the course of millions of years, the human eye has evolved to detect light in the range 380780nm, a portion of the electromagnetic spectrum known as visible light, which we perceive as colour. White light is a combination of all the colors of the visible spectrum, while black is the absence of all light.Ĭomputer monitors mix red, green, and blue colors in order to display a large variety of colors. All-optical 2R-regenerator and wavelength converter experimental setup. A simple tool to convert a wavelength in nm to an RGB, hexadecimal or HSL colour. For example, 400 gives 8300b5, a shade of violet. Note that the visible spectrum is continuous, with no clear boundaries. Enter a wavelength in nanometers between 380 and 780 and get an approximate RGB value. The table below indicates the approximate wavelength range for each color. Colors such as pink, brown, and magenta are absent from the visible spectrum as they are produced by a mixture of multiple wavelengths.Ĭolors that are produced by visible light are called pure spectral color. The visible spectrum does not contain all the colors that the human eye and brain can distinguish. The color ranges from violet through red, with violet having the shortest wavelength. To convert from RGB to the long color code, use the following UDF. Note that I had to multiply the XYZ color by an arbitrary constant to get the results not to be too dark (this is why Im not sure about the normalisation). This small region is known as visible light and has a wavelength range of 350-780 nm. In the visible spectrum red to violet, red has the highest wavelength 650 nm as well as the lowest frequency. ColorConvert can be used to convert the XYZ color to RGB. The human eyes are only sensitive to light which lies between a small region of the electromagnetic spectrum, illustrated on the right.
