The color #1C0090, a deep ultramarine, presents some accessibility challenges, particularly when used as a background or text color. Its low luminance value means that text rendered in this color requires a very light foreground color to ensure sufficient contrast for readability, adhering to WCAG guidelines. Using a contrast checker is essential to verify that the contrast ratio meets accessibility standards, especially for users with visual impairments. A larger font size or increased text weight can help improve readability slightly, but careful consideration of the color pairing is crucial. For interactive elements, consider adding visual cues besides color to communicate state changes, to help accommodate users with color vision deficiencies.
