Nail the exact color slate in your design by using the code from any one of these systems for color identification.
|RGB||r: 192, g: 194, b: 201|
|HSL||h: 227°, s: 8%, l: 77%|
|HSV||h: 227°, s: 4%, v: 79%|
|CMYK||c: 4%, m: 3%, y: 0%, k: 21%|
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, slate is made of 75% red, 76% green, and 79% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 4% cyan, 3% magenta, 0% yellow, 21% black.
