General Information about Persian Blue

Persian Blue, with the hex code #1B3CBB, is a deep, vibrant shade of blue often associated with royalty, sophistication, and tranquility. It is a part of the blue color family, known for its calming and intellectual properties. In color psychology, blue is believed to promote feelings of serenity, security, and order.

It combines a strong blue base with subtle hints of violet, giving it a unique depth and richness.

The color #1B3CBB, or Persian Blue, presents some accessibility challenges, especially in web design. Its relatively low luminance can cause issues when used as text against a white background, potentially failing WCAG contrast ratio requirements for normal text (4.5:1). Using it for large text (at least 18pt or 14pt bold) increases legibility, but careful consideration is still needed. When using this color, provide sufficient contrast by pairing it with lighter colors such as whites, light yellows, or pale greens. Also, think about people with different monitor settings and the color perception. Always test color combinations with accessibility tools to ensure compliance with accessibility standards for all users, including those with visual impairments. Also think about the colorblindness when using the color for interactive elements, think about other ways to make it accesible like adding a label.
