Yes it has chlorophyll
Venus fly trap is green in colour beacuse it has chlorophyll.
It is correct thatpitcher plantsare green in colour as they have chlorophyll and so can photosynthesize. But these types of plants grow in nitrogen deficient soil ( such asswamps or bog areas) unlike other plants. So, to fulfill their nitrogen demand , they trap insects and eat their proteins and this is the reason they are called as insectivorous plants.Pitcher plant can live without insects also but it would be healthier if traps and digests insects. So, Insectivorous plants are partially autotrophic and partially heterotrophic.
