Some people like to pick one main color for their embroidered patches. They try to make sure each patch they use has this color in it so that they all look similar and create an overall solid theme. If you love the color red, you might want to go with a red theme, especially if your motorcycle is red. There are a lot of different colored patches out there, but there are enough red ones that you can make a pretty cool biker theme from them.
If you're a firefighter, it's especially easy to find biker patches that are red. Most firefighter patches have some red on them, and many are predominantly red. There are even some large back patches featuring fire department logos and such.
If you're not a firefighter, don't worry. There are still plenty of red patches out there. Honda, for example, has a number of patches featuring their logos and motorcycles, and since Honda is often associated with the color red, many of these patches are red.
Another option is to look for patriotic patches. They almost always feature the U.S. flag or its colors of red, white, and blue. Many also feature eagles with stars and stripes around them. There are also some military patches, such as the U.S. Marines patch that has a red background on it.
While most sayings patches are done in white, there are some that feature red text and a few that have red die cut borders around them. These patches might be the perfect thing you need to break up some of the images on your jacket.
What's great about doing patches in one main color is that you can mix and match a lot of different images and styles to create a jacket that has a coherent theme but still shows off all aspects of your personality.
