Detailed explanation-1: -Flower colour is largely due to the presence of pigments present in chromoplasts or cell vacuoles of floral tissues.

Detailed explanation-2: -The most common pigments in flowers come in the form of anthocyanins. These pigments range in color from white to red to blue to yellow to purple and even black and brown. A different kind of pigment class is made up of the carotenoids. Carotenoids are responsible for some yellows, oranges, and reds.

Detailed explanation-3: -Explanation: Chromoplasts are coloured plastids found in roots, leaves, flowers and ripe fruits. They contain lipid-soluble pigments, referred to as carotenoids, that provide colour to many different types of plants and flowers.

Detailed explanation-4: -In addition to the important role they play in attracting pollinators and seed dispersers through the coloration of flowers and fruits, anthocyanins are largely responsible for the red colouring of buds and young shoots and the purple and purple-red colours of autumn leaves.
