RGB is perhaps the simplest color system to understand, as the way colors are recorded and reproduced is intuitive and straightforward. If you're new to color theory, this is a good place to start, as it will help you get to grips with some of the more esoteric color systems out there. RGB screens use additive color to create more colors than the human eye can see, but with limitations in display technology, there's still room for improvement.
- [Instructor] Pixels on a screen glow,…combining different amounts of red, green, and blue…to create the impression of a color.…This means the maximum brightness…comes from the combination of those pixels.…Each piece of color information, that's the…red, green, or blue level,…is referred to as a channel,…and you can think of a channel as a separate signal.…You can use two monaural audio channels…to create a stereo mix,…or three monochrome color channels to create full color.…
Keep this word, channel, in mind,…as it's used a lot in reference to…pixel values, radio signals,…audio, or even video streams.…In any case, it'll mean one signal.…The color you perceive…when looking at RGB color information…is created by adding red, green, and blue to black,…from nothing.…This is referred to as additive color,…because you add the red, green, and blue values together…to get the final color.…Gray will always be created…by having an equal amount of all three colors.…
If you're working with eight-bit video,…which runs from zero to 255 for each of the colors,…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
