The Champions Dinner, inaugurated by Ben Hogan in 1952, is held on the Tuesday before each tournament, and is open only to past champions and certain board members of the Augusta National Golf Club. Beginning in 1963, legendary golfers, usually past champions, have hit an honorary tee shot on the morning of the first round to commence play.
In vertebrates and other hemoglobin-using creatures, arterial blood and capillary blood are bright red, as oxygen imparts a strong red color to the heme group. Deoxygenated blood is a darker shade of red; this is present in veins, and can be seen during blood donation and when venous blood samples are taken.
We know that the shape of the heme group and the hemoglobin protein changes, depending on whether hemoglobin is oxygenated or deoxygenated. Therefore, these two conformations must have different light-absorbing properties. Recall that the color of a substance is the complementary color of what it absorbs. The oxygenated conformation of hemoglobin absorbs light in the blue-green range, and it reflects red light. This property accounts for the red appearance of oxygenated blood. On the other hand, the deoxygenated conformation of hemoglobin absorbs light in the orange range, and it reflects blue light.
