Nail the exact color neon green in your design by using the code from any one of these systems for color identification.
|RGB||r: 57, g: 255, b: 20|
|HSL||h: 111°, s: 100%, l: 54%|
|HSV||h: 111°, s: 92%, v: 100%|
|CMYK||c: 78%, m: 0%, y: 92%, k: 0%|
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, neon green is made of 22% red, 100% green, and 8% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 78% cyan, 0% magenta, 92% yellow, 0% black.
