000033

000033 is a hexadecimal color code used in digital color representations. In standard 24-bit RGB color space, the code corresponds to red value 0, green value 0, and blue value 51, or RGB(0,0,51). When expressed as a CSS hex color, it is written as #000033. This combination yields a very dark blue color with low luminance; with blue channel at 51 out of 255, the color appears almost black under many lighting conditions but retains a cool blue tint.

In practice, #000033 is used as a foundation or background color in web and UI design to convey formality and depth; it contrasts strongly with light text. It is distinct from common named blues such as navy (#000080) and darkblue (#00008b), though it is in the same family.

Accessibility considerations apply when using this shade on different backgrounds. On light backgrounds, its contrast with white text remains high, making it suitable for certain headings or accents in dark-themed designs.

Outside of web usage, the color appears in digital palettes and branding as a base tone for corporate materials; it is often paired with lighter blues, grays, or metallic accents to create a subdued, professional aesthetic.
