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, sky blue is made of 53% red, 81% green, and 92% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 43% cyan, 12% magenta, 0% yellow, 8% black.
