The color #0440B0, also known as Cobalt, presents accessibility challenges due to its low luminance.

A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this color for essential UI elements like buttons or links necessitates careful consideration of background colors to avoid making content inaccessible to users with visual impairments. Testing with accessibility tools is crucial to confirm compliance and ensure usability for all users, including those with color blindness or low vision. Designers should consider providing alternative high-contrast themes or allowing users to customize color schemes to improve accessibility. Furthermore, avoid relying solely on color to convey information; use additional cues such as text labels or icons.
