Sonic 1 Color Contrast

By TheInvisibleSun

Dr. Eggman has somehow stolen almost all of the colors (and music) from South Island, and Sonic himself! It is now up to Sonic to return them to where they belong, and restore the island to its colorful musical self.

Sonic's mission is to find the various Color Monitors hidden in each stage. Upon finding them, the various colors and music of the area will begin to be restored to the zone, and he can then proceed to the next act. Collecting every Color Monitor in an act will also allow for Sonic to access the Special Stages to collect the 6 Chaos Emeralds. It is rumored that the Chaos Emeralds grant the power to restore all the colors of an act at once; collect them all to find out! Finding any one of the Color Monitors is required to get through the current act, but you can explore the stages to find them all!

When starting the game, you can select from one or two gameplay modes:


Each zone includes a hub stage, in which Sonic must pass Acts 1 and 3 to continue to the next zone. Each Hub displays the completion status of each act, and can be restored with hidden monitors as well. Complete the stages and explore the hubs to find the elusive Act 2!


Play through each act in a linear order instead, as in Sonic 1-Knuckles.

As an option, Hint Arrows that lead to other monitors, found near each monitor, can be enabled for a less difficult and more accessible gameplay option. This can be enabled at the beginning of Classic Mode, and before every act in Adventure Mode.

The aforementioned Color Monitors include:

*C' (3x): Returns the normal colors to the stage. Each stage includes three of these to track down.
*'Sonic': Reverts Sonic's colors back to normal, and grants 1 extra life.
*'Goggles': Returns all underwater colors to normal, including Sonic's. Labyrinth Zone and Scrap Brain Act 3 only.
*'Music': Changes the background music back to normal.
*'Cycle': Returns all of the cycling palettes (like Green Hill's waterfalls) to normal. There are none of these in Marble Zone.

Note: Only finding one of these is required to complete the Act.

Other helpful Monitors include:

*'Super Ring': Gives you 10 rings.
*'Speed Shoes': Increases Sonic's speed.
*'High-Jump Shield': Increases Sonic's jump height, as well as protects him from one single hit.
*'Restart': Returns Sonic back to the start of the stage.
*'Invincibility': Makes Sonic invincible for a short time.

This build includes 4 Zones--Green Hill Zone, Marble Zone, Spring Yard Zone, and Final Zone. However, future revisions will include Labyrinth Zone, Star Light Zone, and Scrap Brain Zone.

If you want to leave an act early, Hold A, then press Start when paused to return to the Hub Stage from any act.

Explore the zones to find all of the Color Monitors and unlock hidden secrets and extras!
