Here's why:

* Color is not a determining factor for heat conductivity. Color is a visual property related to how a material reflects light. It has little to do with how well it conducts heat.

* Material composition is crucial. The actual material that is silver or white determines its heat conductivity.

* Metals are excellent conductors. Silver itself is an extremely good conductor of heat, while white materials can be made of various substances, many of which are poor conductors (like white plastic or white paint).

Example:

* Silver metal: A very good conductor of heat.

* White paint: A poor conductor of heat.

Therefore, it's not accurate to compare "white color" and "silver color" in terms of heat conductivity. You need to consider the specific material involved.
