Shader code
shader_type canvas_item;


uniform vec4 color: hint_color = vec4(1.0);


float circle(vec2 position, float radius, float feather)
{
	return smoothstep(radius, radius + feather, length(position - vec2(0.5)));
}


void fragment(){
	
	float outer = circle(vec2(UV.x, UV.y), 0.35, 0.01);
	
	float fade_effect = sin(TIME) * 0.01;
	
	float inner = 1.0 - circle(vec2(UV.x, UV.y), 0.275, 0.1 - fade_effect );
	
	COLOR = color;
	COLOR.a -= outer + inner;

THis a new shader code for Godot 4.1.2 to work
I change the code of color to uniform vec4 color= vec4(1.0,1.0,1.0,1.0);

shader_type canvas_item;

uniform vec4 color= vec4(1.0,1.0,1.0,1.0);

float circle(vec2 position, float radius, float feather)
{
return smoothstep(radius, radius + feather, length(position – vec2(0.5)));
}

void fragment(){

float outer = circle(vec2(UV.x, UV.y), 0.35, 0.01);

float fade_effect = sin(TIME) * 0.01;

float inner = 1.0 – circle(vec2(UV.x, UV.y), 0.275, 0.1 – fade_effect );

COLOR = color;
COLOR.a -= outer + inner;

}

Hey i changed the Code a little bit so you can manipulate the values in the shader_parameters, also there is a better color_wheel

shader_type canvas_item;

uniform vec4 color : source_color = vec4(1.0, 1.0, 1.0, 1.0);

float circle(vec2 position, float radius, float feather)
{
return smoothstep(radius, radius + feather, length(position - vec2(0.5)));
}

uniform float outer_radius : hint_range(0,0.7,0.005) = 0.35;
uniform float inner_radius : hint_range(0,0.7,0.005) = 0.275;
uniform float fade_effect_amount : hint_range(0,0.1,0.005) = 0.01;
void fragment(){

float outer = circle(vec2(UV.x, UV.y), outer_radius, 0.01);

float fade_effect = sin(TIME) * fade_effect_amount;

float inner = 1.0 - circle(vec2(UV.x, UV.y), inner_radius, 0.1 - fade_effect );

COLOR = color;
COLOR.a -= outer + inner;

}
