Web Color Guide: From Color Theory to Practical Palettes

The Power of Color

Research shows 90% of first impressions about websites come from color. The right palette can establish brand recognition, guide attention, convey emotions, and improve conversions.

Color Fundamentals

Three Properties - **Hue**: The type of color (red, blue, green) - **Saturation**: Color purity/vibrancy - **Lightness**: How light or dark

Color Formats - HEX: #FF5733 (most common in web dev) - RGB: rgb(255, 87, 51) - HSL: hsl(14, 100%, 60%)

Classic Color Schemes

1. Complementary Opposite colors on the color wheel (blue + orange). High contrast, great for emphasis.

2. Analogous Adjacent colors (blue + teal + green). Harmonious and natural.

3. Triadic Three equally spaced colors. Colorful yet balanced.

4. Monochromatic Same hue with different lightness/saturation. Elegant and foolproof.
