For a dreamy theme, the following colors from the palettes would work well as primary and secondary colors:

Primary Color:

• Serene Blue - #B0E0E6 (from the first palette) or Sky Blue - #87CEEB (from the second palette)
  • Both colors evoke a sense of calm and serenity, making them ideal as a primary color for backgrounds or large elements on the website.

Secondary Color:

• Soft Lavender - #E6E6FA (from the first palette) or Pale Green - #98FB98 (from the fourth palette)
  • These colors complement the primary blue nicely. Soft Lavender adds a whimsical touch, while Pale Green offers a fresh and natural vibe.

Using these combinations will create a balanced and cohesive dreamy aesthetic.
