# X Color Palette Query/Retrieve Service Class

## X.1 Overview

### X.1.1 Scope

The Color Palette Query/Retrieve Service Class defines an application-level class-of-service that facilitates access to Color Palette composite objects.

### X.1.2 Conventions

See Conventions for the Basic Worklist Management Service (K.1.2).

### X.1.3 Query/Retrieve Information Model

In order to serve as an SCP of the Color Palette Query/Retrieve Service Class, a DICOM AE possesses information about the Attributes of a number of Color Palette composite SOP Instances. The information is organized into a Color Palette Information Model.

### X.1.4 Service Definition

Two peer DICOM AEs implement a SOP Class of the Color Palette Query/Retrieve Service Class with one serving in the SCU role and one serving in the SCP role. SOP Classes of the Color Palette Query/Retrieve Service Class are implemented using the DIMSE-C C-FIND, C-MOVE and C-GET services as defined in PS3.7.

The semantics of the C-FIND service are the same as those defined in the Service Definition of the Basic Worklist Management Service Class.

The semantics of the C-MOVE and C-GET services are the same as those defined in the Service Definition of the Query/Retrieve Service Class, with the exception that there is only one level of retrieval.
