Some sepals are green but not all are green. It is a modified leaf that protects the flower bud. But sometimes the sepals have as much color as the petals. In daylilies, there are three petals and three sepals. The sepals may have the same color and pattern as the petals or different.
Generally by the color of their petals(physical property) But the actual "color" is determined by their pigmentaion
The flower petals are bright in color so as to attract pollinators such as insects, birds, and animals to facilitate reproduction in plants.
Anthers are usually bright colored just like the petals. They do not have any particular color.
Primroses typically have 5 petals. Primroses are mostly yellow or cream in color, although there are also pink and white varieties.
