Color vignette

Vignette + color, you can change the color and the alpha of the effect.

You can use this in fullscreen with a TextureRect node.
[!] But don’t forget to add a full white bitmap (or other bitmap 🙂 ) in TextureRect.

Enjoy.

Shader code

shader_type canvas_item;

uniform float vignette_intensity = 0.4;
uniform float vignette_opacity : hint_range(0.0, 1.0) = 0.5;
uniform vec4 vignette_rgb : hint_color = vec4(0.0, 0.0, 0.0, 1.0);

float vignette(vec2 uv){
	uv *= 1.0 - uv.xy;
	float vignette = uv.x * uv.y * 15.0;
	return pow(vignette, vignette_intensity * vignette_opacity);
}

void fragment(){
	vec4 color = texture(SCREEN_TEXTURE, SCREEN_UV);
	vec4 text = texture(TEXTURE, UV);
	
	text.rgba *= (vignette_rgb.rgba);
	text.rgba *= (1.0 - vignette(UV));
	
	COLOR = vec4((text.rgb)*color.rgb,text.a);
}
