Yes (its called black body radiation).
no

Yes, after death at room temperature, the body can undergo a process called livor mortis, where the blood pools and settles in the lowest parts of the body, causing those areas to appear discolored or bruised. This discoloration can give the appearance of the body changing color after death.
Color temperature can be accurately measured using a device called a spectrophotometer, which analyzes the light emitted by a source and determines its color temperature based on the wavelengths present.
The thermostat of the body is the hypothalamus, a region in the brain that helps regulate and maintain the body's temperature around a set point. It receives signals from temperature receptors in the body and can initiate responses to either increase or decrease body temperature as needed.
That is called the TEMPERATURE.
