General Information about Gulf Blue

The hex color #100657, often referred to as Gulf Blue, is a deep, saturated shade of blue residing in the dark end of the color spectrum. It is created by combining a small amount of red (16 in hexadecimal) with a slightly larger amount of blue (87 in hexadecimal) and a minimal presence of green (6 in hexadecimal). This particular combination results in a color that is perceived as both calming and sophisticated, reminiscent of deep ocean waters or a twilight sky. In color theory, #100657 belongs to the blue family, which is generally associated with feelings of tranquility, stability, and trust. Due to its dark nature, it carries a certain weight and can convey a sense of authority and professionalism. Its unique blend makes it a versatile choice for designers and artists alike.

The hex color #100657, also known as Gulf Blue, presents some accessibility challenges, particularly in text and user interface design. Due to its deep, dark nature, it has low luminance, which can create insufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability. When using #100657 for text, it is essential to pair it with very light colors like white or pale yellow to meet these contrast requirements. Failure to do so can result in reduced readability for users with visual impairments. In interface elements, using #100657 as a background color requires careful consideration of the foreground elements to ensure they are easily discernible. Testing color combinations with accessibility tools is highly recommended to validate compliance with accessibility standards and provide an inclusive user experience.
