Why does my set color button not work and turn everything black?

So I wanted to make a theme and when you clicked the button it would change everything into a blue theme. But instead of changing everything into a light blue and dark blue combination everything turns black. Can anyone tell me why? The following code is a part of the theme menu that would change color of a admin GUI on my experimental game.

My code:

-- Color
    
    local DarkerBlue = 53,56,255
    
    local LighterBlue = 101,103,255
