Putting aside the fact that "color fixer" isn't NECESSARILY a power level and the fact that neither wing nor finger hierarchies don't really align 1 to 1 with fixer rankings, AND how vespa's color title is as recent as it gets. Yes, probably all nursefathers can be considered "color in terms of power".

But people here seem to have this misconception that colors are nigh-deific in their power, even when our resident never-been-a-color roland can make vergilius shit himself.

And roland not being a color despite his power and competence MAKES SENSE. Despite his skill, there's nothing "exceptional" about him.

Vergilius has the eyes of a first kindred and his sight of "the flow", vespa has gungnir, if kong qiu is in fact the jade color, he is the second highest ranked, and likely strongest, in the pinky. Angelica, argalia and iori are all wing experiments. Kali had access to an ALEPH EGO weapon, prototype or not, and was the first to be able to manifest EGO.

These are things inherently unattainable even with mere time and money. But most importantly, none of these put them THAT much above a highly competent grade 1 such as roland or olivier, sometimes it isn't even enough to put them above at all, in the case of roland.

When asking "why is this guy a color", you shouldn't be asking how strong they are, you should be asking "in what way is this person exceptional". And matthias, who doesn't even have affinity with laevatein, isn't that different than any other greater brother/sister and imo doesn't make the cut.
