It will be easier to tell them apart as next seasons are in color. And I find the art style change too.
I read the raws to know as english version is not complete.
This webtoon has season 1 and 2 completed already and season 3 still running in korean.

Don't spoil yourself too much, next chapters are very interesting ~
I think it would have been easier if the author has just had one family blonde and one family as the dark hair instead of the alpha has the darker hair and the omega has the blonde hair. I keep thinking the two blondes are brothers and the two dark haired are as well.
Then you add the fiance Matthew is also blonde with a similar hairstyle to the younger omega brother and it gets doubly confusing. If they had considering giving Matthew something more distinct, it would help. Now you got three blondes who look very similar.
I can't tell the younger omega blonde apart from Matthew.
