#666665 Hex Color

#666665 functions as a neutral, but its ash-like quality gives it a slight cool bias compared to warmer, beige-toned greys. This characteristic makes it an ideal background when you want to avoid visual clutter while keeping the design feeling crisp and modern.

Because #666665 is so desaturated, it works as a blank canvas for high-contrast accents like vibrant yellow or deep navy. Using it to anchor bright colors allows those secondary hues to pop without the interface feeling chaotic or over-designed.
