1. Problem Description

The problem consists of several questions related to digital graphics. I am asked to calculate the number of colors in an image, given the number of bits per pixel.

2. Solution Steps

The question asks for the number of colors if a pixel has 6 bits.

The number of colors is calculated by $2^n$, where $n$ is the number of bits. In this case, $n = 6$.

Therefore, the number of colors is $2^6 = 64$.

3. Final Answer

The number of colors used in the image is 64.
