General Information About Hex Color #1B30FD

The hexadecimal color #1B30FD, also known as a vibrant and deep shade of blue, belongs to the blue color family and possesses a high level of saturation. This particular shade of blue is characterized by its intensity and brilliance, making it a popular choice for various applications in design and art. Hex color codes are a way of representing colors in HTML, CSS, and other digital design contexts. The # symbol indicates that the following characters represent a hexadecimal number. The first two characters (1B) represent the red component, the next two (30) represent the green component, and the last two (FD) represent the blue component. In this case, there is relatively little red or green, with a very strong blue component, hence the vibrant blue color. It evokes feelings of calmness, confidence, and clarity. Blue is often associated with trust and reliability, making it a staple in corporate branding and visual communication.

The color #1B30FD, a deep and vibrant blue, presents several accessibility considerations for web developers. Its luminance is relatively low, meaning that text rendered in this color, or UI elements using this color as a background, will require careful attention to contrast ratios. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive content effectively. A light text color, such as white or a very pale yellow, against this blue background is recommended to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Conversely, if #1B30FD is used as a text color, a very light background color should be chosen. Avoid pairing it with dark or similarly saturated colors, as this could lead to readability issues and eye strain. Testing the color combination with accessibility tools is crucial to guarantee compliance and optimal user experience for all users, including those with visual impairments.
