Nail the exact color lime green in your design by using the code from any one of these systems for color identification.
|RGB||r: 50, g: 205, b: 50|
|HSL||h: 120°, s: 61%, l: 50%|
|HSV||h: 120°, s: 76%, v: 80%|
|CMYK||c: 76%, m: 0%, y: 76%, k: 20%|
If you're identifying color for pretty much anything digital, you're working in an RGB colorspace. If the project you're working on requires percentage representation, lime green is made of 20% red, 80% green, and 20% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 76% cyan, 0% magenta, 76% yellow, 20% black.
