Truecolor renderer
From DoomWiki.org
Truecolor is originally a marketing name used for 24-bit color rendering, allowing the display's entire gamut to be simultaneously used. A truecolor renderer allows to display graphics that are not restricted to the game's palette.
Hardware-accelerated renderers (using a rendering backend such as Direct3D, OpenGL, or Vulkan) are truecolor by default, though some may use a palette filter to more closely emulate the classic software renderer's look. It is more difficult to adapt the software renderer to function in truecolor mode.
The main use of truecolor rendering is to avoid color depth loss caused by using the COLORMAP lookup table. The drawback is the loss of certain tricks permitted by such a COLORMAP, such as fading different color ranges in different ways instead of applying a universal formula to all colors.
Other uses of truecolor rendering include better colored lighting, fully accurate translucency, and support for non-paletted assets, such as PNG images.
