The correct attribute to use is ATTR_FRAME_COLOR.
An easy way to interactively discover the attributes pertaining to a specific control is to select the appropriate control type in the first parameter of "Select attribute constant" popup panel, as you can see below: after selecting "decoration" as the control type the list of attributes will show as active the only attributes effectively usable with decorations.
