The hex color #033EB1, also known as Cobalt, presents certain accessibility challenges, particularly in text-based contexts. Its low lightness value (a measure of perceived brightness) means it offers weak contrast against backgrounds, especially white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, particularly for users with visual impairments. To enhance accessibility, avoid using #033EB1 for text on light backgrounds. If used, ensure there is a substantially lighter color such as a bright yellow or a very pale gray as a background. It is more safely used for decorative elements and interface components that do not convey essential information. When creating UI elements, pairing this color with appropriate ARIA attributes to describe its role and purpose can also help improve accessibility for assistive technologies.
