Its relatively low luminance value means that using it as a background color necessitates careful selection of foreground text color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #2B4CBB as a background, a light color like white (#FFFFFF) or a very pale yellow would generally offer adequate contrast.

Thoroughly testing color combinations with accessibility evaluation tools is essential to guarantee compliance with accessibility standards and provide an inclusive user experience. Keep in mind that color perception can vary among individuals, so gathering feedback from diverse users is also beneficial.
