Definition - What does True Color mean?
Techopedia explains True Color
True color also refers to displays or screens that use the RGB display mode and do not need a color look-up table. Each sub-pixel of red, green and blue contains 8 bits of information, and if a fourth byte is present it is used for alpha channel information or simply ignored. If a system has a fourth byte for the alpha channel, this is then referred to as a 32-bit true-color display, which uses the RGBA color display, where "A" is the alpha channel. If a 32-bit display is forced to revert to a 24-bit mode, then the alpha channel is dropped, which disables transparency and translucency effects but has no effect on the color depth, unless it goes further down towards an 8- or 16-bit color depth.
