The color #0A184D, also known as Gulf Blue, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value of 1.7 means that it offers very little contrast against darker backgrounds, making it unsuitable for primary text or important user interface elements. According to WCAG guidelines, this color fails even the most lenient contrast ratio requirements. To ensure readability and usability for all users, especially those with visual impairments, it's crucial to pair #0A184D with very light colors, such as white or pale yellow, for text or interactive elements. When using this color for backgrounds, employing larger font sizes and heavier font weights can partially mitigate the contrast issues, though careful testing with assistive technologies is always recommended. Consider alternative, lighter shades of blue or using a contrast checker tool to verify compliance with accessibility standards.
