It belongs to the blue color family and is characterized by its strong presence and intense pigmentation. In the RGB color model, #151286 consists of 8.24% red, 7.06% green, and 52.55% blue. This composition results in a color that is heavily weighted towards the blue end of the spectrum, giving it its distinctive character.

Today, it is synthetically produced, making it readily available for various applications, including digital design, printing, and manufacturing.

The hex color #151286, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in very low contrast against standard light backgrounds, making text or interface elements difficult to read. To ensure accessibility, web developers should avoid using #151286 for text or interactive elements without employing high-contrast color combinations. A light color, such as a pale yellow or a very light gray, used in conjunction with #151286, can improve readability. Following WCAG guidelines for contrast ratios is crucial. Tools are readily available online to check color contrast ratios and assess whether a chosen color pair meets the minimum accessibility standards. Also, consider providing alternative themes or color customization options to allow users to adjust the color scheme according to their preferences and needs. This is especially important for users with color blindness or other visual sensitivities.
