Think of it as:
* Lighter than chestnut brown: It has more blond in it, preventing it from being a true brown.
* Darker than strawberry blond: While both have red undertones, chestnut blond has more brown and golden blond.
* Warmer than ash blond: Ash blond is cool-toned, while chestnut blond is definitely warm.
Essentially, it's a harmonious combination of blond and light brown shades.
