Nail the exact color whitesmoke in your design by using the code from any one of these systems for color identification.
|RGB||r: 245, g: 245, b: 245|
|HSL||h: 0°, s: 0%, l: 96%|
|HSV||h: 0°, s: 0%, v: 96%|
|CMYK||c: 0%, m: 0%, y: 0%, k: 4%|
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, whitesmoke is made of 96% red, 96% green, and 96% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 0% cyan, 0% magenta, 0% yellow, 4% black.
