You can find the accesssibility options by heading on over to the Settings menu and then selecting the appropiate tab for the setting you are looking for, whether it's;
• "Gameplay" for options such as subtitles, camera & UI Shake
• "Graphics" for FoV, UI options and film grain effect
• "Audio" for the style of sound degredation and audio equalization as well as sound levels
• "Controls" to adjust your keybinds, sensitivity and aim assist

As the game is in black and white, there's currently no colorblind adjustment options.
