Nail the exact color olive green in your design by using the code from any one of these systems for color identification.
|RGB||r: 186, g: 184, b: 108|
|HSL||h: 58°, s: 36%, l: 58%|
|HSV||h: 58°, s: 42%, v: 73%|
|CMYK||c: 0%, m: 1%, y: 42%, k: 27%|
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, olive green is made of 73% red, 72% green, and 42% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 0% cyan, 1% magenta, 42% yellow, 27% black.
