If you are referring to why blood goes from bright red in the aorta to a darker reddish-purple in the pulmonary artery, the answer is because the blood has lost the majority of the oxygen it was carrying. This causes a conformation change in the carrier hemoglobin, which results in a color change. If you are referring to another color change in the blood (such as why a particular animal's blood is chocolate brown, for example), this would be due to a toxicosis and the animal should be taken to a vet immediately.
Ribosomes in a animal cell are the color of brown.
click on the picture of your animal in the bottom left corner. A menu showing your animal and a color pallet will pop up. Use the color pallet to change your color, eyes, and patterns. If you have any, you can also put on clothes from here.
