But these levers aren't as one dimensional as sporting a single predetermined pigment, for the chemical properties of the metal used would be altered during manufacturing to produce a heat-responsive effect as soon as the surface is touched. Depending on the temperature of the user's skin, the Thermosensitive Handle can take on a full spectrum of bright neon tints that differ according to the prior placement of the palm and fingers.
