Hi, I have bought cotman series by winsor and newton.. i painted swashes but i am having a hard time telling if a color is cool or warm.. i know what color bias is cool or warm… but how to tell what bias they have… if any one can help me with the blues only

ultramarine

cerulean blue

intense blue

prussian blue

cobalt blue

bear in mind these are cotman winsor and newton blues… how to deter their temperature 🤒
