Misc. Author Info       : I enjoy customizing the vanilla engine and
                          pushing it as far as it can go.

Description             : CopperPal is a drop-in replacement for the stock
                          Doom palette. It should be compatible with all
                          WADs that do not change the palette significantly
                          (e.g. Ancient Aliens, BTSX, etc).
                          
                          The goals of CopperPal are:
                          
                          1. Increase contrast slightly, such that darker
                          areas look better and more color-accurate. It
                          also just makes the colors "pop" a bit more.
                          
                          2. Modify colors to blend together better such
                          that the COLORMAP is more visually harmonious.
                          
                          The biggest example of the problem (2) aims to
                          solve are the reds (and pinks) in Doom's stock
                          palette -- the darkest red is only about 25%
                          brightness, and as such, becomes brown in the
                          dark, which is very noticeable. Most palette
                          mods simply extend the red ranges to be darker;
                          this does the job, but the contrast is quite
                          harsh on IWAD assets, and, in my opinion,
                          doesn't look too good. It also doesn't solve
                          the same issue that the oranges have.
                          
                          CopperPal solves this by embracing the Doom
                          palette's strength: brown. The reds are gradually
                          hue shifted towards a slight orange, and
                          desaturated very slightly. The browns themselves
                          are saturated and red-shifted a bit. This results
                          in a much more pleasant color blend that looks a
                          lot nicer and less abrupt than Doom's stock
                          COLORMAP. The orange-shifting of dark reds also
                          consequentially benefits the oranges as well.
                          
                          Revision one fixes issues with contrast with the
                          browns, greys, and greens. Golds and greens were
                          tweaked to be a bit more vibrant compared to
                          before.

                          scratch.
