If you like them feel free to reference or use the colours.
Now for Anime eye tips? ( these are merely my opinion and derived from my own experiences)
Your characters eyes can say a lot about them, whether you want them fierce or kind, mysterious or bold, eyes are a great way to show character and help portray personality.
I find evil/fierce eyes tend to be sharper and more elongated in shape, while kinder eyes are generally more curved with a flatter bottom and a more curved top. To create a more intense eye, giving the iris a dark out line and making the pupil very small tends to do the trick ^^!
Animes eyes are also extremely varied from semi realistic to chibi, and allow for a lot of creative flexibility. Just keep in mind the basics when drawing the eye. It is not flat, instead it is more of an oval/circular shape and when viewing from the side is is visibly curved with the cornea creating another curve on top of the globe. Also it is important to remember to give the eye lids thickness.
I recommend becoming more familiar with the anatomy of the eye, find some good photos or diagrams to see what is what, and what goes were.
Well hope this is helpful
