#66A9B0 Hex Color

Because Timid Sea has a low-chroma, ashy quality, it pairs most effectively with charcoal or deep slate grays to ground the color. Using a high-contrast dark neutral prevents the cyan from feeling washed out and ensures text remains highly legible for users.

The hex color #66a9b0 provides solid readability when used as a background behind standard black text. However, you should avoid placing white text over this color, as the contrast ratio is typically insufficient to meet WCAG AA standards for small text sizes.
