layer use true color or index color?

[sunlight1]

Hi 
How can i know if Object layer is True color or Index color? 
for example, lets say i have an object list or layer list and i want to change the IC layers to TC layers, 
and the TC layers to IC layers. 
so how/where can i get that info about that ?

(getpropertyvalue (tblobjname "layer" "YourLayerName") "Color")

returns a text string, of three numbers with commas between for Truecolor, just one for index.
