Variations in paper and ink processes account for the various combinations of non-invertible matrices and look-up tables used in converting from RGB to CMYK. If you wish to obtain CMYK values for these colors, you will get appropriate conversion values from your graphics application when you define the type of ink and paper you will be printing on.
The Adobe RGB (1998) color space or opRGB is a color space developed by Adobe Inc. in 1998. It was designed to encompass most of the colors achievable on CMYK color printers , but by using RGB primary colors on a device such as a computer display .
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: cyan, magenta, yellow, and key (most often black).

As an RGB system, it describes the amounts of red, green, and blue light which are added together in order to create a particular color. Every color infobox on Wikipedia must have one such parameter to, at the very least, show on the screen an idea of what the color looks like.
The ECI-CMYK color space, sometimes written ECI CMYK or eciCMYK, is a standardized CMYK color space for graphic data exchange in the print industry. It is equivalent to Fogra 53, often spelt FOGRA53, and is intended to overcome limitations of and thereby replace the ISO Coated CMYK exchange color space (version 2 = Fogra 39, version 3 = Fogra 51).
Unlike the RGB and CMYK color models, CIELAB is designed to approximate human vision. The L* component closely matches human perception of lightness, though it does not take the Helmholtz–Kohlrausch effect into account. CIELAB is less uniform in the color axes, but is useful for predicting small differences in color.
To see how this works in practice, suppose we have a particular RGB and CMYK color space, and want to convert from this RGB to that CMYK. The first step is to obtain the two ICC profiles concerned. To perform the conversion, each RGB triplet is first converted to the Profile connection space (PCS) using the RGB profile.
