Analogous colors sit next to one another on the color wheel, creating a harmonious scheme with relatively little contrast. section 17.6
Build an analogous palette with HSL hue values:
- Start with a main hue, then add 30 degrees for one color and subtract 30 degrees for the other. section 17.6 section 17.7
- Use 15-degree differences when you want even less contrast. section 17.6
- For a more contrasting scheme, make one hue dominant and reserve the other two for buttons, borders, and accents. section 17.6
A red-based palette
Red, hsl(0, 100%, 50%), is analogous to hsl(30, 100%, 50%) and hsl(330, 100%, 50%). section 17.6
Figure 17.11 Use the Web Design Playground’s Color Scheme Calculator to generate a color scheme for a given RGB code.
Use the Color Scheme Calculator to choose a starting color and generate its analogous palette, including RGB, rgb(), and hsl() values. section 17.7
