Due to its low luminance value, it can appear almost black in certain lighting conditions. Its desaturated nature contributes to a sense of subtlety and sophistication, making it a versatile choice for designs that require a muted and understated palette.

The color #0A3030, also known as Firefly, presents several accessibility challenges in web design. Its low luminance value of approximately 2.7 cd/m² falls significantly short of the WCAG recommended contrast ratios for text and non-text elements. When used as a background color, it necessitates very light text (e.g., white or near-white) to achieve sufficient contrast. Even then, careful consideration is required to ensure readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0A3030 for crucial interactive elements, such as buttons or links, demands even greater attention to contrast and alternative visual cues, like borders or icons. It's crucial to assess the color's impact on users with color blindness, as its dark, desaturated nature might cause confusion or make it difficult to distinguish from other dark hues. Thorough accessibility testing with diverse user groups and assistive technologies is essential when incorporating #0A3030 into a design to prevent usability issues.
