Blue hues - cold and warm definition

[lene]

Hi
Does anybody have an idea which blue hues to place in either category: colder and warmer ... ? Some of the blue colors I feel pretty sure about. Like warmer; ultramarin blue, violet blue

I am in doubt when looking at colors like Cerulean blue, True Blue, Copenhagen Blue ... even indigo

Cerulean is a yellow blue and Indigo is a red/purple blue guess those would be warm :confused:
