It is a color commonly used in corporate branding, particularly in industries such as technology, finance, and healthcare.

The human eye perceives blue due to specific cone cells in the retina that are sensitive to blue wavelengths of light. This color can evoke feelings of calmness and serenity.

The color #1E3BB5, also known as Persian Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low lightness value (around 12%) means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). When using #1E3BB5 for text, ensure that the background color is sufficiently light to meet these contrast requirements. Lighter shades of gray, yellow, or even light blues and greens can provide adequate contrast. Tools like contrast checkers can be used to verify compliance. For interactive elements like buttons or links, consider providing additional visual cues, such as underlines or borders, to enhance distinguishability. Also, avoid using #1E3BB5 for important information where color is the sole means of conveying meaning.
