RGB interface transfers image data using a separate parallel line for each bit of color information. Different numbers of lines are used depending on the color depth. For instance, a full 24-bit data bus includes 8-bits/color, which is 256 possible values for reach Red, Green, and Blue color data. That means over 16 million possible colors can be described.

For 18-bit RGB each color has 6 lines, leading to approximately 262,000 possible colors. R5G6B5 or 565 describes up to 65,000 colors.

RGB lines include the different color lines, HSYNC, VSYNC, DE, and DOTCLK.
