Nail the exact color red orange in your design by using the code from any one of these systems for color identification.

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, red orange is made of 100% red, 33% green, and 29% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 0% cyan, 67% magenta, 71% yellow, 0% black.
