An embedded systems engineer is designing a low-power digital instrument display. The display currently uses a color depth of 4 bits per pixel. To support a new user interface theme with a wider range of colors, the firmware must be updated to support at least 1,000 1,000\,1,000 distinct colors.
Select the minimum increase in the number of bits allocated per pixel (color depth) required to achieve this.
555 bits
666 bits
101010 bits
121212 bits
