If instead you want the output color space to be linearized Adobe RGB (1998), then you can use the rgb2lin function. For example, to convert CIE 1976 L*a*b* image LAB to linearized Adobe RGB (1998) color space, perform the conversion in two steps: All you need to match your RGB and color data with paint, ink, color standards and commercial color collections. Use the form below to convert color data across different color standards and color spaces (RGB, CMYK, L*ab, L*ch, L*uv, Hunter, XYZ etc.).May 05, 2009 · Function RGBToHSB(rgb As RGBColor) As HSBColor Dim minRGB, maxRGB, Delta As Double Dim h, s, b As Double h = 0 minRGB = Min(Min(rgb.Red, rgb.Green), rgb.Blue) maxRGB = Max(Max(rgb.Red, rgb.Green), rgb.Blue) Delta = (maxRGB - minRGB) b = maxRGB If (maxRGB <> 0) Then s = 255 * Delta / maxRGB Else s = 0 End If If (s > 0) Then If rgb.Red = maxRGB ... Colors can be entered by specifying the hue (H), chroma (C), and luminance (L) values via sliders, by entering an RGB hex code, or by clicking on a color in the hue-chroma or luminance-chroma plane. It is also possible to select individual colors and add them to a palette for comparison and future reference. The code used for the Rgb and Lab conversions can be found on Github: RgbConverter.cs; LabConverter.cs; Conversion Example: var rgb = new Rgb(); var lab = rgb.To<Lab>();

Jan 04, 2019 · The Adobe RGB gamut is larger, particularly in the green and cyan colors. It allows for more saturation (“chroma”) in those areas. ProPhoto RGB is the largest of the three – and possibly the most interesting, since it includes “colors” outside what we can see. We call these imaginary colors just to induce fear in other photographers ...

The CIE Lab color space is approximately perceptually uniform, and so gives smoother and more uniform color ramps. On the other hand, palettes that vary from one hue to another via white may have a more symmetrical appearance in RGB space.
Colors can be entered by specifying the hue (H), chroma (C), and luminance (L) values via sliders, by entering an RGB hex code, or by clicking on a color in the hue-chroma or luminance-chroma plane. It is also possible to select individual colors and add them to a palette for comparison and future reference.
