I can help here.
You have some options. Personally, I simply rattle can things a light shade of coyote brown and then add some random stripes in a dark tan. Camouflage is ALL about breaking up your profile, not about becoming invisible. As a lifelong hunter and also a veteran of the outdoor industry who built a hunting apparel brand, I can say with confidence that the most effective patterns are the simplest. Break up the outline; don't try to look like a shrub.
The post above is correct--many animals don't see orange. Stay away from blue, however. Be aware that birds absolutely see color and will shy away from anything unnatural. But yes, assuming you're not shooting turkeys or other prey birds, it can never hurt to war an orange hat, especially in the fall.
Your other option is to buy camo tape on Amazon--that is if it won't interfere with the telescoping legs. They make tape that can be removed.
Here are a few of the more effective patterns for reference. Notice it's all about breaking up your shape and not actually looking like a tree or a leaf.
