Nail the exact color neon blue in your design by using the code from any one of these systems for color identification.
|RGB||r: 77, g: 77, b: 255|
|HSL||h: 240°, s: 100%, l: 65%|
|HSV||h: 240°, s: 70%, v: 100%|
|CMYK||c: 70%, m: 70%, y: 0%, 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 blue is made of 30% red, 30% green, and 100% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 70% cyan, 70% magenta, 0% yellow, 0% black.
