Please don't use "lighter" and "darker" colors to signal importance. The contrast on these is invariably too low for most displays, and people miss that cue completely. What's lighter for you has the exact same color/intensity for most users. It's the same with "material design" where some genius decided that buttons no longer need to look like buttons, and links no longer need to look like links. Sure they don't. And users sure don't need to know what can be done with the interface. But what's the point? /rant
