The hex color #030656, often referred to as Gulf Blue, is a very dark shade of blue falling into the blue-violet color spectrum. It is composed of 1.18% red, 2.35% green, and 33.73% blue. In the RGB color model, it is represented as RGB(3, 6, 86). Its HSL values are 236 degrees for hue, 93% saturation, and 17% lightness. The color is characterized by its deep, intense saturation and very low lightness, contributing to its overall darkness. This color is often associated with depth, stability, and sophistication. Gulf Blue finds applications in various design contexts, but its darkness requires careful consideration of contrast and readability to ensure accessibility and visual appeal.

The hex color #030656, also known as Gulf Blue, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value of 0.003 makes it a very dark color. When used as a background, it necessitates extremely light text colors to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. For example, using white text (#FFFFFF) provides a contrast ratio of approximately 70:1, which far exceeds the minimum requirement of 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold). However, less intense light colors might fall short. Designers should avoid pairing this color with mid-tone grays or any dark hues as text colors. In user interface design, using this color for interactive elements like buttons or links requires careful consideration to ensure sufficient visual distinction and to provide clear focus indicators for keyboard navigation.
