Reference notes
As a reference color, #2E8B57 reads as balanced green, with Sea Green as its nearest named anchor. Because the hue is approximately 146 degrees, it belongs to the green family rather than a neutral family, even when used in small interface details. When documenting the color, keep the hex value as the canonical reference and treat the balanced family label as a practical visual description rather than a fixed rule. The contrast checks on this page show whether it is more reliable with black text or white text, which is usually the first practical decision before using the color in UI. The modification grid is useful for finding a border, hover, or background companion without changing the underlying hue family too aggressively. For data visualization, avoid relying on this color alone; combine it with spacing, labels, or pattern differences so meaning is not carried only by hue. Use it for backgrounds, supporting UI surfaces, editorial layouts, and restrained visual systems. Check contrast before placing body text on top of it, and pair it with nearby analogous colors when the design should stay calm.
