When it comes to paint, the toxicity refers to a pigment's propensity to cause cancer, illness or death. These are typically the pigments that contain heavy metals such as lead, cadmium, chromium, manganese, cobalt, etc. The warning regarding inhalation typically concerns the use of a diluted mixture in an atomizer or airbrush. It does not refer to smelling the paint. A well ventilated area is recommended with any medium. This could be no more than a window that is barely open to let fresh air in. I've lived in Michigan and understand the weather conditions. A small space heater can be used on cold days to counteract the cold air coming in through the window.

Not all pigments are considered toxic. If that is a concern, there are acceptable substitute pigments in any paint line.
