Color is usually some shade of yellow and often varies with the concentration of the sample. The most common color descriptions of normal urine are straw, light yellow, yellow and dark yellow. Amber colored urine is seen in patients with increased bilirubin levels and may indicate hepatitis.

The league-wide batting average has generally ranged between .250 and .275, and players with batting averages above .300 are considered to be very good batters. A batting average of .400 over a season is considered to be the ultimate achievement by a batter and is nearly unattainable in modern baseball.
