RGB and CMYK

When it comes to images, there are two kinds of color used in most programs. These are known as RGB, and CMYK. I did not have to go too far down the list of resources on the teacher's blog to understand the meaning and differences of each color type.

RGB
RGB color stands for red, green, and blue. By using any combination of varying amounts of each of these three colors, you can literally make millions of different shades of color. RGB is known as additive. This means that the more color you add, the lighter the shade will be. Pure red, green or blue will always be the darkest shade you can get. As you blend all together, you eventually get the color white. RGB is often used for online images, since it's simpler than CMYK.


CMYK
CMYK color stands for cyan, magenta, yellow, and black. Unlike RGB, which uses values between 0 to 255 for each color, CMYK uses percentages from 0 to 100 for each color. By combining different percentages of cyan, magenta, and yellow, you can make vast amounts of different color. Further unlike RGB, CMYK is known as subtractive. This means that the more color of each type you add, the darker the image will get. With 100% of each color, you will get true black. For this reason, CMYK is the preferred color type for printing, and people often convert their work from RGB to CMYK if they weren't already doing so before printing their work.

Personally, I don't favor either color type over the other. Both have their advantages. RGB looks better in my opinion, and I prefer its 0-255 system over that of CMYK's, but the latter is more favorable when it comes to printing, so it is better in that sense.
