I was just watching a video about Thermochromic Pigments. I started wondering, What if I were to paint some of my PC parts with this stuff? Even just the fans?

"Thermochromic pigment change color or become invisible at a particular temperature in this case 25°C (77°F). Some may refer to thermochromic pigments as "heat sensitive pigments". Limitless combinations and effects can be achieved with thermochromic powder.
Color changing pigments can be used for print, plastic molding, resin casting, painting, screen printing and much more! Cover a design or pattern that will be revealed once the correct temperature is reached. Or even create new colors by mixing thermochromic powder with an already tinted paint and create a color changing effect. Use our clear acrylic paint with glow powder to make your own glow in the dark thermochromic paint.
Thermochromic pigments have a micron size of 0.01 and are encapsulated. Encapsulation makes it waterproof so it won't be destroyed or dry out the medium you chose to mix it into. It is non-toxic but should never be ingested or put in direct contact with the eyes, nasal or ear passages, or mouth."
I don't know much about thermodynamics, but I am wondering, how would this effect temperatures of certain parts? What other issues may I be concerned about if I try this?
Other questions; could a manufacturer make parts (Like watercooling tubes) that have Thermochromic properties?
