Below is a row of images of seven slightly different grays. Only one is a neutral (with no colour cast) gray. Can you tell which one it is?

Row of grays

The image is made up of a row of images of slightly different grays (1050 × 300 dots). If you cannot see the boundaries between the grays there is probably a problem with the display environment or gradation expression of your monitor. What we mean by this is a normal colour or monochrome gradation image should be smoothly reproduced.  If there is a problem with the gradation expression it produces things like blocked-up shadows in dark areas and blown-out highlights in light areas, banding (vertical or horizontal stripes) in the middle gradations and colour cast.

The answer to the question asked above is 'the far right' so if the other grays looked correct, colour may not be being correctly recognised for a variety of reasons, which includes the lighting environment or the LCD settings.

For example, when the room is lit with standard household incandescent lights white and gray look reddish, while fluorescent lights can make them appear green. Plus, as mentioned in our previous article, white and gray can have a reddish tinge when the monitor has been set to a low colour temperature, while a high setting can give them a bluish tinge.
