If you mess up, you can click start over to return to the original image. 3. Paste your picture below (right click on the widget and hit copy) 6-bit colors (64 unique colors) 4. Set bits/pixel to 6 and experiment with each of the R, G, and B values. At 6 bits/pixel, it means each color channel has 2 bits assigned to it, so there are 4 possible shades of each of R, G, and B.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
