Can one be Cool toned with blonde hair and brown eyes?
Yes you can have cool skin with any coloring but Cool may not be the primary color characteristic.
Blonde hair and brown eyes is often associated with some of the Northern European countries but with migration it's obviously far more widespread than that.
The fairness and gentle coloring associated with a Cool skin and light brown to blonde hair may suggest that either the Light Color Family or the Muted Color Family gives the most pleasing palette overall.
The Cool tones within those palettes could be your best shades.
