The largest has a diameter of just over 10 km or an area of 69000 Olympic swimming pools.

Ceres' visible albedo is 0.090±0.0033, that is pitchblack. Use your favorite graphics editor to compare R/G/B=0/0/0 with R/G/B=23/23/23 to convince yourself. I do not know how white the "white" spots are.

Beer because Ceres was the goddess of grain crops.
