That has its explanation. Although it may sound a bit difficult, understanding what the difference is between RGB and CMYK color is pretty straightforward. Below we will help you discover it, through very simple definitions and examples. Even if you have an Ubuntu operating system, you can install a Picker color selector , which will help you better distinguish between RGB and CMYK color.
Definition, use and example of RGB color
RGB color is used in electronic devices : screens, televisions, laptops, cell phones, projectors, internet, YouTube videos, etc. The RGB code is the systematization of the following colors in English: red (red), green (green) and blue (blue).
These three colors are universal, which means that, from the combination of these three, you can get basically any color you can imagine, and when you overlap them, you get absolute white. By using them in the aforementioned electronic devices, you achieve a product or image with great intensity.
To achieve the creation of thousands of colors, what you must do is control, both red, green and blue, their hue, lighting, and saturation. Even with the Photoshop application you can convert the index to RGB without losing the quality of the image very easily. Working all this in the base colors, and combining them we can achieve many colors. As in the example that we see below:
RGB is an additive color, in other words, to get a new and intense color, you have to add the red, green and blue. And to achieve absolute white on a black surface we must unite these three colors at their best.
With these details we can understand why the screens of cell phones, computers, or monitors, when they are off, are totally black. The reason is that RGB colors are absent, so no color is created.
Definition, function and example of CMYK color
The CMYK color is used in the prints. Knowing this is extremely important, since if you choose RGB colors at the time of printing, a color conversion to CMYK will be carried out automatically, which will give you unexpected results because the toner, or the ink of the printers, does not have shades of that intensity.
If you do not pay attention to this setting, you will end up having different, less intense colors in your impression than what you saw on the screen. For example, if you use applications like CorelDRAW or Corel Photo Paint to create a Mandala , you can level the CMYK colors, to have a better image resolution. The following example will help you see it more clearly:
CMYK is short for the following colors: cyan, magenta, yellow, and key black. CMYK color is rendered underlying, or as a result of, RGB colors.
To create the colors that you want to be reflected in your print, you must control, as well as in RGB, the shades, saturation and lighting of cyan, magenta, yellow.
To achieve absolute white in this case, the CMY colors must be hidden or removed. If we want to achieve black, the CMY colors must be joined or overlapped. But an absolute black is not achieved, so the KEY representing black must be increased.
With the combination of these four colors, you will be able to obtain any new color of the visible spectrum.
With the Corel Photo Paint application you can apply color transformation effects to your images, you can even choose the color parameters, RGB or CMYK. Also, you will have the opportunity to obtain combinations and tones that stand out and are not so common, which will turn your images into very original designs.
