This Code system is used in the following value sets:

• ValueSet: Color Codes (Names or RGB Values) (This value set includes color codes - either the color names as defined in CSS4 , or any valid RGB code (#RRGGBB in Hex).)

---

4.3.2.31.1 Definition

RGB values for color. Valid codes are #RRGGBB where RR, GG, and BB are two letter hex codes, values 00..ff. codes are case insensitive. This code system does not define the 16million+ valid RGB codes (terminology servers will need code to support the RGB grammar).

Explanation of the columns that may appear on this page:

Level	A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
Source	The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code	The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display	The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition	An explanation of the meaning of the concept
Comments	Additional notes about how to use the code
