In other areas of the spectrum, the reverse is true. Especially problematic: In some areas of the visible spectrum, the RGB color space lies outside the CMYK color space.

One of the most challenging aspects of professional printing is converting RGB color from a computer into matching CMYK color for the press. (The K in CMYK stands for black.) CMYK color is common to color printing, which is why that process is often referred to as “four-color printing.” As with the RGB color model, CMYK color is based on dots of just a few colors - in this case, cyan, magenta, yellow and black. When they are, the RGB color model then produces an absolute color space, such as Adobe RGB.ĬMYK.

Also, the RGB color model itself does not define the specific red, green or blue used, so a given RGB color can’t be exact unless the spectral makeup of the three primaries are defined. Here’s where RGB gets tricky: The pixels in various computer monitors display red, green and blue differently, so what you see on one screen rarely matches what you see on another. For example, 85 107 47 in the RGB color model equals a dark olive green. Common to color models used for computer monitors and television screens, the RGB color model depends on the human eye to “mix” dots (or pixels) of red, green and blue. Let’s take a look at three of the most common color models, as well as their typical applications. To do that, you need a basic grasp of color models: the different mathematical formulas (based on component colors) for defining color spaces. Sometimes getting the sofa to match the paint requires the ability to move back and forth between color spaces. RGB (red green blue) is an example of a color space. For a design professional, the challenge lies in the multitude of color spaces available, each based on a different combination of colors and values. If you’ve ever struggled to reproduce a color from one project to another, or to “translate” a particular color from a swatch of fabric to a can of paint, then you’ve experienced firsthand the challenges associated with something called “color space.”Ĭolor space refers to the particular universe of colors made possible from combining three or four basic colors, or from adjusting hue, saturation and brightness. Do color-matching frustrations have you seeing red? Don’t get mad, get a color model instead.
