The color #100D0A, also known as Cod Gray, presents significant accessibility challenges, especially in web design. Its extremely low luminance of approximately 0.008 makes it difficult to distinguish from pure black (#000000). Consequently, using #100D0A as text or as a primary background color is strongly discouraged due to poor readability. According to WCAG guidelines, it fails all contrast ratio tests against white text, meaning it does not meet even the minimum accessibility standards. To ensure accessibility, it's imperative to pair #100D0A with much lighter colors that provide sufficient contrast. When used for decorative purposes, careful consideration should still be given to the surrounding colors to avoid any visual impairments for users with low vision or color blindness. Tools for checking color contrast ratios can assist designers in making informed decisions.
