What colour granules does a basophil have?

Explanation:
Basophil granules are blue because they bind basic dyes used in standard cytological stains. This blue coloration reflects the granules’ chemical properties and distinguishes basophils from other granulocytes (eosinophils stain orange-red, neutrophils are pale). The granules contain histamine and heparin, which is why these cells consistently appear blue under routine staining.
