What is the first target presented when testing for color deficiency?

1. 2

2. 1

3. 3

4. 4

The correct answer is: 1

When testing for color deficiency, the first target presented is designed to establish a baseline or a reference point for the individual's color perception abilities. Presenting the first target typically involves using a number, symbol, or shape that is easily distinguishable from the background and serves as an initial task for the test subject. This helps to gauge their ability to perceive colors accurately. In many color vision tests, the first target often represents a standard or commonly understood reference, making it easier for individuals to respond accurately. The choice identified as the first target is chosen to be the most straightforward, facilitating an effective testing process that reduces potential confusion or frustration in the participant. Subsequent targets are designed to challenge the individual's color perception and identify specific types of color deficiencies based on the responses to an array of different colors and patterns. Starting the testing with a clear, easily perceivable target helps ensure that the assessment is conducted smoothly and reliably.
