The hex color #100D33, also known as Black Rock, presents some accessibility challenges due to its low luminance. When used as a background color, it is crucial to select a text color with high contrast to ensure readability for users with visual impairments. A light text color such as white (#FFFFFF) or a very light gray would be suitable choices. Tools like contrast checkers can help determine if the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using this color for elements that require precise visual distinction, such as interactive controls, without careful consideration of the contrast. For users with cognitive disabilities, avoid using this color in large areas that cause eye strain.
