The color of Shrek is primarily a distinctive shade of green. Specifically, "Shrek Green" is a vibrant and bright green with a hex code of #C4D300 in design color systems. The RGB values for this color are (196, 211, 0), making it a yellowish-green tone. This unique green is what's commonly associated with Shrek's skin color in the character's depiction. Additionally, the reason Shrek's skin is green, biologically speaking in a fictional sense, is due to the presence of a green bile pigment called biliverdin, which is more prevalent in Shrek's body compared to humans who have more red bile pigments. This gives him the distinct green rather than pinkish or brownish skin tones.
