In your fanfiction perhaps. Not in Kishimotos story.
-Minatos nickname was the "Yellow Flash".
When he moves, his yellow hair leaves a streak of light in his path. This is specifically for movement, not teleportation. There is no light in teleportation. Light can't escape. When Minato teleports, there is no streak, light, or anything. When Tobirama teleports, there is no streak or light. When Sasuke teleports, there is no streak or light. When Obito teleports, there is no streak or light. When Kaguya teleports, there is no light or streak. When Minatos guards teleports Mei, there is no light or streak. When someone or something is summoned, there is no streak or light.
When Ay moves, we see a blue streak/light. When his father moves, we see a blue streak/light. When Gai and Lee move with Gates, we see a green streak/light hence their nickname's, the "Green Beast" and "Green Devil" of Konoha. When KCM Naruto moves, we see a streak/light. The first time Killer Bee called his speed similar to the "yellow flash" Kakashi thought he was the Yellow Flash. When Tsunade seen Narutos shunshin against Ay, what she say? Oh, "Just like the Yellow Flash!" When Bee saw it, what'd he say? "That really looked like the Yellow Flash"
What stands out about all the people who leaves streaks/light/afterimages? They're physically moving. Minato was so fast without teleportation he left streaks which is where his name comes from. Hirashin doesn't leave streaks or afterimages, no light escapes from teleportation, it's from his natural speed like the rest of them.
Ay admitted Minato was faster than him. Ay can dodge Amaterasu. That means Minato can dodge Amaterasu too, even better, because he'll sense it coming long before. But of course none of these facts mean anything to you because fuck what the author writes.
