I trained this model on the character Sakura Rui from Shikijou Kyoudan.

I took images from a visual novel and hentai.

I'll go into a little more detail for the hentai version. Rui's hair color changes slightly,

as in the anime she is blonde, while in the visual novel her hair has an orange tint in addition to blonde.

I separately put out the prompt for the visual novel and anime (hentai) versions.

Visual novel (Original)

ruisa, 1girl, multicolored hair, blonde hair, orange hair, long hair, side ponytail, 
swept bangs, purple eyes, large breasts, dark-skinned female, pink lips, light blue nails,

Hentai

ruisa, 1girl, blonde hair, long hair, side ponytail, swept bangs, purple eyes, 
large breasts, dark-skinned female, pink lips, light blue nails, 
anime screencap, anime coloring,

In fact, the color of her blazer is closer to cyan, however, for some reason it is inconsistent.

Sumeragi Kohaku is one of the best artists.
