Abstract
A toy vehicle spray painted with paint containing thermochromic material which changes color as the temperature of the vehicle varies. Selected portions of the toy vehicle may be painted with the thermochromic material to provide a variety of patterns, designs, numbers, letters or other indicia which change color in response to temperature variations. In addition, different portions of the toy vehicle may be painted with different paints containing different color thermochromic materials.
