What is the relationship between file size and color depth?
As color depth increases, file size decreases.
As color depth increases, file size increases.
Color depth has no impact on file size.
File size only depends on the image dimensions.
Explication
More colors (higher color depth) typically require more bits to represent each pixel, hence larger file sizes.
