How can I effectively pair #78be21 in a design interface?
This aggressive green thrives when balanced against dark, neutral tones like charcoal or matte black, which ground its intensity. Use it sparingly for call-to-action buttons or interactive elements to ensure the user's eye is drawn immediately to important actions without overwhelming the layout.
Is #78be21 suitable for text or background usage?
Avoid using #78be21 as a background color for large text blocks, as its high luminosity often violates WCAG contrast guidelines for accessibility. It works significantly better as a graphical flourish, a highlight color for data visualization, or an active state indicator on darker, high-contrast surfaces.
Is #78be21 readable on white or black?
#78be21 has a 2.28:1 contrast ratio on white and 9.18:1 on black. WCAG asks for 4.5:1 for body text and 3:1 for large text, so on white it is too faint for text and on black it works for body text. Try other pairs in the contrast checker.
