Overview
Digital images store color information in channels, which are grayscale images representing color elements. The color mode determines how colors combine based on the number of channels in the model.
Color Fundamentals
- Traditional primary colors are red, blue, and yellow, taught from a young age.
- Digital images use different primary colors and systems to create full-color displays.
- Color creation in digital formats differs from physical paint or pigment mixing.
Color Channels
- Channels are grayscale images storing information about color elements in an image.
- Each channel represents a specific color component of the overall image.
- The number and type of channels depend on the image's color mode.
- Channels work together to produce the final visible colors in an image.
Color Modes
Common color modes include RGB, CMYK, and Greyscale. Each mode has different applications and uses.
| Component | RGB Color Model |
|---|
| Channels | Red, Blue, Green |
| Color Type | Additive primaries |
| Primary Use | Computer monitors and digital displays |
- RGB model creates colors by combining red, blue, and green channels.
- Most computer monitors use RGB mode to display colors on screen.
- CMYK is another common color mode used in design work.
- Greyscale mode uses only brightness values without color information.
Key Terms & Definitions
- Channels: Grayscale images that store information about color elements in a digital image.
- Color Mode: System determining how colors combine based on the number of color channels.
- Additive Primaries: Primary colors that create new colors when combined; RGB uses this principle.
