Pretty well any bright colour, but we have to bear in mind that a bee's colour vision is different from our own. They can see ultra-violet light, which we can't, but are not able to see light from the red end of the spectrum, their vision sensitivity starting at around orange.
No, colours don't make bees sting. They sting in response to a perceived threat either to themselves or to their colony.
Bees are attracted to flowers' scent and bright colors.
Bees only eat pollen and nectar and they are attracted to nectar-bearing flowers by their scent and their colours. They make honey from the nectar, and will eat this when nectar is not available. Beekeepers may take the honey, and replace it with sugar syrup which the bees find equally acceptable.
bees are attracted to drinks like orange and grape soda.
Yellow and Black
yes
Bees are attracted to palm trees when they are in bloom (flowering). Bees are naturally attracted to flowers, as flower's pollen is their energy source.
Bees do need to collect water, for drinking and to cool the hive. They are not especially attracted to salt water.
Although this may seem over-simple, bees are attracted by scent and by the colours. However, bees don't see the colours as we do. Their colour vision extends well into the ultra-violet part of the spectrum and is less sensitive to red. They can see patterns in the petals that we can't, and these patterns guide them to the nectar. This attraction would also explain why bees will come and investigate you if you are wearing flower-scented perfume.
Flowers attract bees by their scent and beautiful colours they have.
Bees are attracted to colors as well as scents. The flowers of the ginger plant attract birds more so then bees as the pollen is located to deep in the flower.
Two hypotheses about bees and flowers might include that bees are attracted to purple flowers. Another one could be that bees are attracted to flowers that are brighter colors instead of dark colors.
