The ____ color model operates with three primary additive colors: red, green, and blue. Each channel can have intensity levels ranging from 0 to ____, which is an 8-bit value. Combining all three channels with 256 levels each results in over ____ possible colors. This means that each pixel in an RGB image requires ____ or 3 bytes of data, representing the total color depth.
