General Information about #130A21 (Ebony)

The hex color #130A21, often referred to as Ebony, is a very dark shade of purple-blue. In the RGB color model, it is composed of 7.45% red, 3.92% green, and 12.94% blue. This composition gives it a subtly cool undertone. It is typically perceived as a sophisticated, mysterious, and even luxurious color. Due to its very low luminance, it appears almost black. Ebony often conveys feelings of depth, elegance, and understated power. In design, it's used to create a strong and grounded aesthetic, evoking a sense of calm and authority. Because of the low luminance value, using this color as a background requires careful consideration of text and element contrast to ensure accessibility.

The hex color #130A21, also known as Ebony, presents specific accessibility challenges due to its dark nature. When used as a background color, it necessitates very light text (ideally white or near-white) to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. Insufficient contrast can make content difficult or impossible for users with visual impairments to read. Using contrast checking tools is crucial to verify compliance. Additionally, avoid using #130A21 to convey important information solely through color, as colorblind users may not be able to perceive it. Provide alternative cues like text labels or icons to ensure inclusivity.
