8a but you might have to tweek it. Sometimes it’s warm when it come in and other times it’s cool. If you have any other color you might use more than one.
I usually like to get 2 colors. But I was reading about all the matting and mine have actually been doing it so all of it makes me so nervous.
I have done quite a bit and not had any issues. Knock on wood.
It was 8A btw! Incase anyone needs help with a color like this.
