What color does urine appear in macroscopic hematuria?

In cases of macroscopic hematuria, urine typically appears red to brown due to the presence of significant amounts of blood in the urine. This discoloration is primarily caused by red blood cells, which can alter the clear or yellow color of normal urine to shades of red, brown, or even tea-colored, depending on the concentration of blood and the duration of exposure to urine. Macroscopic hematuria indicates that the blood is visible to the naked eye, often resulting in a noticeable change to the urine's appearance that is distinct from the normal colors of clear, yellow, or other unusual colors like dark green, which are indicative of different conditions or substances in the urine.
