The hex color #1555B5, also known as Tory Blue, presents some accessibility considerations for web development. Its luminance value is relatively low, which means it may not provide sufficient contrast against lighter backgrounds. When used as text color, it's crucial to ensure a contrast ratio of at least 4.5:1 against the background color to meet WCAG AA standards. For large text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Using a color contrast checker is highly recommended to verify compliance. Avoid pairing this color with very light shades like white or pale yellow, as this could cause readability issues, especially for users with visual impairments. Consider using it with darker shades of gray or black to enhance contrast and ensure accessibility for a wider range of users.
