The color #181C18, also known as Rangoon Green, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 4.3 cd/m² means that text rendered in this color against a black or very dark background may be difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color may not meet these contrast requirements when paired with many background colors, necessitating careful consideration of color combinations. To ensure accessibility, it is advisable to use lighter text colors such as white or very light grays when using #181C18 as a background. Additionally, providing alternative cues beyond color, such as text labels or icons, can enhance usability for all users, especially those with color vision deficiencies. Testing with accessibility tools is highly recommended to confirm sufficient contrast and overall usability.
