Can an on/off switch be used to change between different LED colors?

Can an on/off switch be used to change between different LED colors?
I was wanting to convert a White LED flashlight to one with multiple colors.
How can I use the tail cap on/off switch to change between the 3 or more colors?
[on one color / off / on next color / off / on next color etc...]?

Yes that is true. But what kind of chip? And where could I get / use it?
idk. it is an old tech where the chip is dipped in some sort of black epoxy.
however u can program a pic to do it.
