Well the squirrels (or chipmunks)ate all of my white crocus but left the light and dark purple ones...so I'd believe that there is some type of preference on how they look or taste...

had same thing with tulips and deer
loved the purple but left the yellow

I'm not sure about the deer's taste/color preference. But my younger brother would only eat the pink tulips taht I fed him and never the purple ones.

myb the deer get to the pink ones first and get full before they get to other colors? It;s probably because the pink one's are your favorite that the deer only eat those to irritate you. although deer grazing thru the garden problably is irritating enough. have you considered irritating the deer back by eating them?
