In metal processing, the metal turns blue due to a process called tempering. Tempering is a heat treatment technique used to increase the toughness and reduce the brittleness of the metal. During tempering, a thin oxide layer forms on the surface of the metal, giving it a blue color. This color change is a visual indicator that the metal has been properly tempered and is now more suitable for certain applications. Additionally, the metal may also develop a rainbow-like iridescence, known as tempering colors, which is a result of the thin oxide layer reflecting light at different wavelengths. **

In "Spider-Man: No Way Home," Electro is depicted as yellow instead of blue to differentiate him from his appearance in "The Amazing Spider-Man 2." This change in color may have been made to give the character a fresh look and to better fit the darker and more realistic tone of the Marvel Cinematic Universe. Additionally, the yellow color may have been chosen to make Electro visually distinct from other blue-colored characters in the film, such as Doctor Octopus and the Lizard. **
