Eosin Y, also known as Eosin yellowish is a widely used xanthene dye. It is a counterstain that is used to distinguish between various connective tissue fibers and matrices, and the cytoplasm of different types of cells. Eosin in combination with hematoxylin is useful to demonstrate the general histological architecture of a tissue.

Bromocresol Green (BCG), also known as bromcresol green, is a synthetic, anionic, triphenylmethane dye belonging to the phthalein and sulphonphthalein dyes group. It is commonly used as a pH indicator as it changes colour from yellow to blue-green at pH 3,8 to 5,4. The monosodium salt of bromocresol green is highly ionisable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.
