As a general rule, RGB colors are used for digital displays and CMYK colors are used for printing. However, there are some important differences between the two color models that you should be aware of when working in Photoshop.
RGB (Red, Green, Blue) is the color model used for digital displays such as monitors and TVs. The colors are created by combining red, green, and blue light. This is the “additive” color model because you add light to create the colors.
CMYK (Cyan, Magenta, Yellow, Black) is the color model used for printing. The colors are created by combining cyan, magenta, yellow, and black ink. This is the “subtractive” color model because you start with white paper and remove color from it.
One of the biggest differences between RGB and CMYK is that RGB has a wider range of colors than CMYK. This means that you can create more vibrant and bright colors with RGB than with CMYK. However, CMYK can still produce a wide range of colors, just not as many as RGB.
Another difference between RGB and CMYK is that RGB colors are made up of pixels while CMYK colors are made up of dots. When an image is printed using CMYK inks, each pixel is actually made up of tiny dots of cyan, magenta, yellow, and black ink. The human eye perceives these dots as a solid color.
So what’s the best color model to use? It depends on your project.
If you’re creating an image for digital display (such as on a website or blog), then use RGB. If you’re creating an image for print (such as a flyer or business card), then use CMYK.
In general, RGB colors are used for digital displays and CMYK colors are used for printing; however, there are some important differences between the two color models that users should be aware of when working in Photoshop. Some of the key differences include: (1) the range of colors that can be produced by each model – RGB has a wider range of colors than CMYK; (2) how the colors are made up – RGB colors are made up of pixels while CMYK colors are made up of dots; and (3) what effect each model has on human eyesight – due to its construction, images viewed on digital displays may appear more vibrant and bright than those printed using CMYK inks. Ultimately, which color model to use depends on the project being undertaken; if creating an image for digital display purposes then use RGB while if creating an image for print then use CMYK.
