B. Using Color Names
In addition to hexadecimal colors, JavaScript allows you to use predefined color names. For example:
element.style.color = "green";C. Using Hexadecimal Color Codes
Color codes can be defined using hexadecimal values. The format is #RRGGBB. For example:
element.style.color = "#FF5733"; // A shade of orangeD. Using RGB Values
RGB values can be expressed with rgb(int, int, int) where each integer ranges from 0 to 255:
element.style.color = "rgb(0, 128, 0)"; // GreenE. Using RGBA Values
RGBA includes transparency in addition to RGB. The syntax is rgba(int, int, int, alpha) where alpha ranges from 0 (fully transparent) to 1 (fully opaque):
element.style.color = "rgba(255, 0, 0, 0.5)"; // Semi-transparent redF. Using HSL Values
HSL defines colors in terms of hue, saturation, and lightness. The syntax is hsl(hue, saturation%, lightness%):
element.style.color = "hsl(240, 100%, 50%)"; // Bright blueVI. Related Properties
