General Information about Gulf Blue

Gulf Blue, represented by the hexadecimal color code #000157, is a very dark shade of blue. It resides in the blue color family but is characterized by its deep and almost imperceptible lightness. The color has minimal presence in the visible spectrum and is therefore primarily appreciated for its depth and potential as an accent. Its RGB values are R:0, G:1, B:87, indicating a very low intensity of red and green light, with blue being the predominant component, though still at a low intensity. In the CMYK color model, its approximate values are C:100, M:99, Y:0, K:66. While not frequently used as a primary color due to its dark nature, it can add sophistication when implemented with careful consideration of contrast and surrounding colors.

The hex color #000157, also known as Gulf Blue, presents significant accessibility challenges due to its very dark nature. Its extremely low luminance results in poor contrast against standard light backgrounds, making text and interactive elements difficult to perceive for users, especially those with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability and usability. To improve accessibility, it's essential to pair this color with very light colors such as white (#FFFFFF) or very light shades of yellow or green. When using #000157 for text, ensure that the contrast ratio meets at least 4.5:1 for normal text and 3:1 for large text. Providing alternative color schemes that offer better contrast is highly recommended to accommodate users with different visual needs. Tools like contrast checkers can help assess and adjust color combinations for optimal accessibility. Consider also providing high-contrast mode options for users who require them.
