Many colors begin with the letter O, but the real heavy hitters are “orange,” “old,” and “olive.” While several other o-words crop up multiple times in this group, the word “orange” and its variants appear more than twenty times! The rest comprises various plant, animal, and place names that evoke a wide range of images and colors. No matter what shade you’re looking for, this collection should help you with your search.
Here’s a list of colors that start with O, including names, Hex, RGB, and CMYK codes:

The first entry on our list, Oak is a dark shade of brown with warm red and deeper brown highlights running beneath the surface—a nod to the steady, sturdy brown of old oak timber or oak furniture.
