<p>RGB images use three colors, or <dfn class="term">channels</dfn>, to reproduce
colors on-screen. In 8‑bits-per-channel images, the three channels
translate to 24 (8 bits x 3 channels) bits of color information
per pixel. With 24‑bit images, the three channels can reproduce
up to 16.7 million colors per pixel. With 48‑bit (16‑bits-per-channel) and
96‑bit (32‑bits-per-channel) images, even more colors can be reproduced per
pixel. In addition to being the default mode for new Photoshop images,
the RGB model is used by computer monitors to display colors. This
means that when working in color modes other than RGB, such as CMYK,
Photoshop converts the CMYK image to RGB for display on-screen.</p>
