That's correct! Arterial blood, which is oxygenated blood that has just left the lungs and is on its way to the body's tissues, has a brighter red color than venous blood, which is deoxygenated blood that has released its oxygen to the tissues and is returning to the lungs.
This is because arterial blood has a higher concentration of oxygen, which binds to the hemoglobin in red blood cells, causing them to appear brighter red. In contrast, venous blood has a lower concentration of oxygen and a higher concentration of carbon dioxide, which causes the hemoglobin to appear more purplish or blue.
This difference in color is often referred to as the "arterial-venous color difference" and can be seen when looking at the color of blood in arteries and veins. For example, arterial blood in the aorta (the main artery that carries blood from the heart to the rest of the body) appears bright red, while venous blood in the superior and inferior vena cavae (the main veins that return blood to the heart) appears more purplish or blue.
