When you come to a point that you want to create a dark translucent container on top of a colourful background, we all notice how desaturated it becomes, and how i.e. Apple seems to negate that. And after having tried each blend mode, it just doesn’t give us 1 blend mode to rule them all and have your container be how you want it to turn out when changing the background to a dark grey background.
So instead of messing around with blend modes, how about the backdrop-filter saturate gets introduced in Figma, and bring back some colour?
