This is a simple mod that changes the background color entry for Green Hill Zone's palette. This change is based on the Sonic 1 (2013) mod Sonic 1 Forever. Here are both palettes as shown in SonLvl:

Original palette from Sonic 1

New palette based on Sonic 1 Forever (S1 2013 mod)

The only color that's changed is the first color on the third line. Typically, every first color on each row serves as a transparent color entry that we never see on-screen. This allows our sprites to appear as various shapes instead of boring collections of squares. The specific color entry we edited serves another purpose, however. This palette entry regularly serves as an all-encompassing background color. In the case of Green Hill Zone, the developers used it to color in the water in the background. Sonic 1 Forever chose to make it a color in-between that of the original Green Hill Zone, and the darker blue Title screen water.
