The hex color #123c89, also known as Congress Blue, presents some accessibility challenges. Its relatively low luminance can make it difficult to read against lighter backgrounds, especially for users with visual impairments. According to WCAG guidelines, sufficient contrast between text and background is essential for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #123c89 for text requires careful consideration of the background color. Light shades of yellow, orange, or even very pale blues might provide adequate contrast.

Also, avoid using color alone to convey important information; always provide alternative cues such as text labels or icons.
