Luigi
An electric, high-energy vibrant green

Luigi is an intense, high-saturation green that demands immediate attention. Due to its extreme brightness, it works best as a 10% accent color for calls to action rather than a large background field. It pairs surprisingly well with deep charcoal grays, which ground its electric energy. Black text remains readable against this hue. The hex code for Luigi is #4cbb17.

How should I use the #4cbb17 Luigi green in a UI design?
Because #4cbb17 is so highly saturated, it works best as a surgical 10% accent color for primary buttons or notification badges. Avoid using it as a large background fill, as its high-voltage intensity can quickly overwhelm the viewer and cause eye strain.
Is Luigi readable on white or black?
Luigi has a 2.49:1 contrast ratio on white and 8.42:1 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.
