Color plays a crucial role in web design, affecting the overall look, feel, and user experience of a website. Here are some key color concepts and terminology:
Color Models
- RGB (Red, Green, Blue): Represents colors by specifying the intensity of red, green, and blue components (0-255).
- HSL (Hue, Saturation, Lightness): Represents colors using hue (the color itself), saturation (the intensity of the color), and lightness (the brightness).
- HSLA (Hue, Saturation, Lightness, Alpha): Similar to HSL but includes an alpha channel for transparency.
Color Properties
- color: Sets the color of text.
- background-color: Sets the background color of an element.
- border-color: Sets the color of an element’s border.
- outline-color: Sets the color of an element’s outline.
- color-scheme: Specifies the preferred color scheme for the page (e.g., light, dark).
Color Theory
- Primary colors: Red, yellow, and blue.
- Secondary colors: Green, orange, and purple (created by mixing primary colors).
- Tertiary colors: Created by mixing a primary color with a secondary color.
- Complementary colors: Colors opposite each other on the color wheel (e.g., red and green).
- Analogous colors: Colors that are adjacent to each other on the color wheel.
- Monochromatic colors: Different shades of the same color.
Color Contrast
- Sufficient contrast: Ensure that text and background colors have enough contrast to be readable for users with visual impairments.
