Im blind to viktor?

so I was in a game where I got smashed by a Viktor, mostly because I wasn't able to see him properly? it was very weird but his hue wasn't really registering in my brain O.o now, I know it's entirely my fault but has anyone faced this problem as well?

it was as if he was a grey blob and I conciously thought of not paying attention to him even though he was dealing a LOT of dmg O.o I'm really surprised, at times he was even besides me and my focus would be on the enemies ahead and even when I saw him it took me like a second to realize what was there :S:S
