UE5 doesn't natively support any dynamic colored translucent shadows - only the path-tracer and baked lighting offer this feature. But using a home-cooked shadow and color pass we can create our own. We do with by capturing the color of our object, and the depth of our scene from the perspective of the sun, and re-projecting that color using an emissive decal. Since light is additive, this should faithfully re-introduce the colored light.
