Seaweed

#21280C

General Information

The hex color code #21280C represents a very dark shade of green, often described as 'Seaweed'. It belongs to the green color family, but its low luminance value makes it appear almost black in certain contexts. In the RGB color model, it consists of 13% red, 16% green, and 5% blue. This color is typically associated with nature, earthiness, and tranquility, but its darkness requires careful consideration when used in design. It's important to note the perceptual qualities of this color, as its perceived brightness and contrast can vary depending on the surrounding colors and lighting conditions. The name 'Seaweed' suggests a connection to marine environments and evokes a sense of depth and mystery.

The hex color #21280C, also known as Seaweed, presents significant accessibility challenges, especially in web design. Its low luminance value results in poor contrast against both white and black backgrounds, making it difficult for users with visual impairments to read text or distinguish elements using this color. According to WCAG guidelines, sufficient contrast is essential for readability and usability. To improve accessibility, it's crucial to use #21280C sparingly and pair it with much lighter colors that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Furthermore, avoid using this color as the sole indicator for interactive elements, as users who are color blind may not be able to perceive them. Providing alternative visual cues, such as icons or text labels, can enhance accessibility for a broader audience.
