Nail the exact color bright yellow in your design by using the code from any one of these systems for color identification.
|RGB||r: 255, g: 170, b: 29|
|HSL||h: 37°, s: 100%, l: 56%|
|HSV||h: 37°, s: 89%, v: 100%|
|CMYK||c: 0%, m: 33%, y: 89%, k: 0%|
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, bright yellow is made of 100% red, 67% green, and 11% blue.
If you're identifying color for a print project, you're most likely using a CMYK colorspace—the percentages are 0% cyan, 33% magenta, 89% yellow, 0% black.
