Pretty much every part of the body has a colour some where along a spectrum between a yellowish off white to a dark, almost blackish red. Textbook images of cells from different organs will have been stained with different dyes to make the cell organelles more clear. The most common stain will probably be the H&E stain which makes everything look pink and purple.
