In Methyl Green-Pyronin Y staining, what color do goblet cells display?

Explanation:
In Methyl Green-Pyronin Y staining, DNA binds the green dye and appears green, while RNA binds the red dye and colors pink to red. Goblet cells are mucus-secreting and have cytoplasm rich in mucin, which is acidic and binds methyl green strongly. Because their cytoplasm is dominated by mucin rather than extensive RNA, the red pyronin Y staining is minimal in these cells. As a result, goblet cells primarily show the green color from methyl green, giving a mint green appearance. Their nuclei also stain green because of DNA.
