The Tetradic color scheme is used for rich and versatile designs by combining two pairs of complementary colors.

Steps to generate the Tetradic Palette:

• Step 1: We convert the base color #C8DAEA to HSL to get 208°, 44.74%, and 85.10%.
• Step 2: The tetradic hues are calculated as 208° + 90° = 298°, 208° + 180° = 28°, and 208° + 270° = 118° (wrapped within 0-360°).
• Step 3: We keep the same saturation and lightness and convert 298°, 28°, and 118° back to HEX, resulting in #e9c8ea, #ead8c8, and #c9eac8.
