[BB80] Wizl Color Design Update

認為純白上衣事實上和Wizl的角色設定方向不一至
因此做了一些色彩的方案,最後選擇了這種藍
並不肯定這種色的實際名稱,在觀感上,像是沈在海底的岩石,在個性和背景上非常適合Wizl

I thought that the pure white top was not really in line with Wizl's characterization.
So I did some color schemes and finally chose this blue color.
I'm not sure of the actual name of the color, but it looks like a rock under the sea, which suits Wizl's personality and background very well.
