The color #00105D, also known as Gulf Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 0.004 makes it difficult to perceive against most backgrounds. According to WCAG guidelines, this color fails all contrast ratio tests for normal text (4.5:1) and large text (3:1) against both white and black backgrounds. To ensure accessibility, it is strongly recommended to avoid using #00105D for text or interactive elements. If this color is essential for branding purposes, consider using it sparingly and only in non-essential visual elements. When used, provide sufficient contrast by pairing it with very light colors such as white or very light grays, and implement alternative text descriptions for images or other graphical representations. Also, providing alternative color themes or allowing users to customize their color preferences will improve the usability for people with low vision or color blindness.
