What is Photoshop's color space

Color space in Photoshop

Hi, I'm learning photoshop image processing software, but I'm confused about all the common color spaces in Photoshop. Inject RGB, CMYK, and so on, what is their usefulness?

The most common color space is RGB (red, green, blue) and CMYK (cyan, magenta, yellow, black) Two modes, others are more common HSB (hue, saturation, brightness), lab and so on. These color modes in Photoshop determine the standard values for screen display and printer print files. First of all, when the professional image processing workers in processing RGB images, often encounter an annoying problem, that is the accuracy of color. Because RGB images are often inconsistent results because of the different input devices that are matched. Such problems often plague the unprofessional image workers. Color space can also be regarded as a basis for color management, as long as you can understand its meaning and production process, and adjust the settings, and then color conversion, you can get accurate color mode. However, regardless of the color mode, you need to accurately correct the display, and according to different printing requirements and make the corresponding separations. Through these color patterns, should be able to show the best color, accurate control of color reproduction. Of course, Longge that learning Photoshop does not need to delve into the concept of color space, master some basic methods of operation and the use of filters is the key.
