A visual cue that bone meal won't work

One of the many frustrating things for players is when they use bone meal on a sapling, but they end up wasting an entire stack because they don't realize that there is not enough space and mistakenly think that they are just unlucky. Because of this, there should be some indication when using bone meal on something that the requirements for growth aren't met. My idea is that if bone meal is used on a sapling (or other bonemeal-able block) but the space/lighting/etc. requirements are not met, the particles from using bone meal will look different (maybe the same shape but colored red instead of green) so that it's clear when it's not growing because the requirements are not yet met vs. not growing because it needs more bone meal.
