Here's I have answer for your question.
Blood is the fluid present in our body.it is red in color. As Blood contains haemoglobin. Each unit of haemoglobin is made up of proteins hemes which gives blood red color. More specifically, heme can bind iron molecules, and these can bind oxygen molecules.The blood cells are red because of the interaction between iron and oxygen molecules.
Overall blood is red in color bcoz of the presence of haemoglobin. Some animals do not have haemoglobin so their blood is not in red color.
