Real-World Application: RGB Colors
Web Color Codes: #FF5733
This hex code defines a color using Red, Green, Blue values:
- FF = 255 red (maximum)
- 57 = 87 green (medium)
- 33 = 51 blue (low)
Result: A bright orange-red color. Each color channel is 0-255 (00-FF in hex), giving 16.7 million possible colors (256 × 256 × 256).
Why hex? "#FF5733" is much shorter and cleaner than "rgb(255, 87, 51)" and maps perfectly to binary (2 hex digits = 1 byte = one color channel).
