She is a supporting character from Mugendai (無限大)'s "Panic Princess" (ぱにっく🤍プリンセス), which was serialized in COMIC Attōteki during the 1990s.
I do not know her exact coloring, as there is only one color illustration of her drawn.
In case you are interested, I have written the colors of the illustrations in the prompts, but you are welcome to color them however you like.
Recommend strength is 0.8-1.0 with "retro artstyle, 1980s (style)".
