Which factor is NOT considered in determining the construction materials for fuel tanks?

The selection of construction materials for fuel tanks is critical for ensuring their effectiveness and safety over time. Factors like corrosion resistance, compatibility with the stored fuel, and durability and strength are essential considerations. Corrosion resistance is important to prevent degradation from the fuel or environmental conditions. Compatibility ensures that the material does not react negatively with the fuel, which could lead to leaks or contamination. Durability and strength are necessary for the tank to withstand physical stresses and maintain integrity.

In contrast, the color of the tank does not impact its structural performance or safety. While color may have aesthetic or regulatory implications in some contexts, it does not affect how well the tank functions in relation to the stored fuel or how well it withstands environmental factors. Therefore, color is not a critical factor when determining the appropriate materials for constructing fuel tanks.
