However, its low brightness makes it important to consider accessibility and contrast when using it in design.

The hex color #101901, also known as Green Waterloo, presents significant accessibility challenges due to its very low luminance. Its dark nature results in poor contrast against standard light backgrounds, making it difficult for individuals with visual impairments to discern text or graphical elements. According to WCAG guidelines, it fails all contrast ratio tests for normal-sized text against white (#FFFFFF). To improve accessibility, it is highly recommended to pair it with much lighter colors, ideally whites or very light shades of yellow or green, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using it for critical interface elements or informative text without proper contrast adjustments. Consider alternative, brighter greens for better usability.
