[Star Wars] Why are blaster bolts so visible?

It seems like it would be a really big problem that every time you shoot you draw a giant, glowing line to where you fired from. Are the glowing colors an unavoidable part of the technology? Or was this an intentional design decision?

it's a side effect. Blaster bolts are just magnetically contained plasma, and plasma will always glow brightly. Maybe you could design a weapon that shoots plasma that only radiates in infrared or ultraviolet, but that may not be possible.
