Palette Filter and Pixelate combined

This is just two shaders combined, resulting in the background in my pic.

 

Here are the projects separately

Shader code
shader_type canvas_item;

uniform bool flip ;
uniform sampler2D gradient : hint_black; // It can be whatever palette you want
uniform int amount = 40;

void fragment(){ 
	vec2 grid_uv = round(UV * float(amount)) / float(amount);
	vec4 col = texture(TEXTURE,grid_uv);
	
	float lum = dot(col.rgb,vec3(0.2126,0.7152,0.0722)); // luminance
	
	col = texture(gradient,vec2(abs(float(flip) - lum),0));
	
	COLOR = col;
}
