change color of some items for "one click" watering

I like to use the "one click" watering feature when my harvester is not active. Normally, the ones that don't need watering turn green. That is OK for most crops, but not, say, lilies and some others (a few event crops, for example). When that is the crop is can be very hard to see what does and does not need watering. Not impossible, but just sometimes difficult. What about changing the "need water" color to a blue instead. Its unlikely that would be a base color for most crops and also is appropriate to water.

I realize this might not seem like a big deal, but I think the fix would be small and it would help us older folks a lot.
