Chromoplast is synonymous with chromoplastid, but the first term is more commonly used by modern botanists.

A chromoplast is type of plastid found in more complex vascular plants. These organelles lack chlorophyll but are full of accessory pigments like carotenoids; thus, they are responsible for the bright orange, yellow, and red colors of fruit like tomatoes and cherries, fall leaves, and vegetables like carrots and red peppers.

Chromoplasts can sometimes develop from chloroplasts when the latter lose their chlorophyll. Chromoplasts are roughly the same size as chloroplasts, but due to internal structural differences, they are are much more angular and come in a variety of shapes.
