Aviancore is an aesthetic that is based off anything to do with birds, feathers, wings, freedom, air, or any avian creatures. This does not include mythical beasts, such as griffins, wyverns, phoenixes, etc. This aesthetic is associated with the ideas of freedom and peace, as birds often represent such ideas. Aviancore is not based on a specific time period or country.
Navy, black, white, gray, blue, indigo, and any pastel or faded colors are the colors most commonly seen in this aesthetic. Some colors that aren't as common, but still included, consist of beige, tan, and most other tones of brown.
Patterns that are commonly associated with this aesthetic include any feathery patterns, cloudy or blurry patterns, and arrows (as in bows and arrows).
