That initializer expression isn't dependent on anything other than
RGBColor, and can be compiled to static values (initialized static storage).
Compare and contrast:

What are the definitions for:
kTBMaxConst?
kTBCtrlIdxNew and cmd_New?
kTBCtrlIdxOpen and cmd_Open?
kTBCtrlIdxSave and cmd_Save?
Can they be compiled as static values, or is code generated to initialize
the array?
Tracking those down may be informative.
