Ways to Define Colors in CSS

CSS supports several methods for defining colors:

• Color Name (e.g., red, blue, green)
• Hexadecimal Code (e.g., #ff0000)
• RGB Function (e.g., rgb(255, 0, 0))
• RGBA Function (e.g., rgba(255, 0, 0, 0.5))
• HSL Function (e.g., hsl(0, 100%, 50%))
• HSLA Function (e.g., hsla(0, 100%, 50%, 0.5))
