RGB Color Model
The RGB color model is an additive color model that represents colors by specifying their red, green, and blue components. The combination of different intensities of red, green, and blue light can produce millions of visible colors. In the RGB model, each color component is assigned an intensity value ranging from 0 to 255, where 0 indicates the complete absence of that color and 255 indicates maximum intensity.
The hex code notation represents these RGB values in hexadecimal format (base 16). So #00ff00 breaks down as:
- 00 – Red value (0 out of 255)
- ff – Green value (255 out of 255)
- 00 – Blue value (0 out of 255)
