In some panels her eyes are lighter like the duke's, but in others they're darker like in the first couple chapters. It could be the lighting or just general inconsistencies in the art.
The gem effect is still there, even in the most recent chapter. They just simplify it to be slightly more flat probably for time's sake. They've been doing this since the beginning.

Am i tripping or did her eyes change shade? Her eyes now are a similar shade to the dukes and the sons, brighter and more cyan like than blue. She had normal blue eyes with gem like properties at the start, the chromatic abberation in the eyes disappeared too; her eyes a plain shade of cyan now.
Sorry for being fussy about it i just like staring at their eyes so i couldnt help but notice the difference
