The hex color #045195, a deep, saturated blue, presents some accessibility challenges, particularly when used as a background color with light text. Its low luminance value results in a low contrast ratio against standard white text, potentially making it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Therefore, when using #045195 as a background, it is crucial to use a very light color for the text or consider using a darker shade of blue with a higher luminance for a better contrast. Employing tools that measure contrast ratios can help ensure compliance with accessibility standards, creating a more inclusive user experience. To improve accessibility, consider using lighter shades of yellow, orange, or even very light grays as text color, or use #045195 as text color on light backgrounds.
