Its low luminance value means it offers very little contrast against lighter backgrounds, making it difficult for users with visual impairments to discern text or other elements using this color.

To ensure accessibility, it is imperative to avoid using #100b21 as text color on white or light-colored backgrounds.

Consider using this color as a background color only with light text to maintain a reasonable contrast ratio and consider the amount of text on that background.
