Neat!
This is oddly specific to something I had in mind as a game feature, thanks!

Can add sunrays too?

How do I decrease the blur and how do I change the color of the blur while underwater?

Example:

Before Blur:

After Blur:

Change the blur and color stuff here in the script

Glitches when you die underwater. So, I made a fix that prevents that:
Relocate the script from StarterCharacter to StarterPlayer

local player = game:GetService("Players").LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")

humanoid.Died:Connect(function()
	UnderwaterAmbienceSound:Stop()
	ColorCorrection.Enabled = false
	Blur.Enabled = false
	game.SoundService.AmbientReverb = Enum.ReverbType.City
end)

It works fine with no extra changes when its in StarterPlayerScripts, I edited the post to say StarterPlayerScripts instead of StarterCharacterScripts, Idk why I had it in StarterCharacter
