A little @codepen demo I made some years back: #duotone a B&W image using pure #CSS #blending (and very little code in total) https://codepen.io/thebabydino/pen/MWbdbrm

With a comparison slider between the two blend modes that may be used for the effect and a picker for duotone palette base.

Created for my Taming Blend Modes #CSSTricks article https://css-tricks.com/taming-blend-modes-difference-and-exclusion/
