The color #152233, also known as Firefly, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 2% means that text rendered in this color against a white background would have a very low contrast ratio, failing WCAG standards for readability. To ensure accessibility, it's crucial to use #152233 with light backgrounds or text colors to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color as the sole indicator for interactive elements like links or buttons, as users with color vision deficiencies may not be able to distinguish them. Providing supplementary cues, such as underlines or icons, can significantly improve usability.
