I want to "colorize" my whole website without changing individual color settings (i.e. monochrome canvas tint "lens?" [closed]

However it is so extensively complex that Iw ould like to globally change the website colouring so the entire page, including images buttons and logos or texts, share the same hue. is this possible with one command somehow? I'm quite frustrated at having to recolor it, its too much work...
