shader_type canvas_item;
void fragment(){
	vec3 palette[] = {vec3(0)}; // Can be any list of RGB colors, but there must be at least one.
	vec3 color = texture(TEXTURE,UV).rgb;
	vec3 new_color = palette[0];
	for (int i = 0; i<pallete.length(); i++){
		if (distance(palette[i],color) < distance(new_color, color)){
			new_color = palette[i];
		}
		COLOR.rgb = new_color;
		COLOR.a  = texture(TEXTURE,UV).a
