Colors are one of the easiest things to "Negotiate" you simply explain that the wrong color means no signature on that all important line, If they can not deliver the color you want, NO Signature..
Now to a Salesman there is one and only one problem. NO SIGNATURE
So he will make sure you get the colors.
I have to agree I like the induction cooktop.. here is a surprise.
I've cooked in cast iron on gas and electric many times,, You need a pot holder to touch the handle.. But on the induction cooktop.. Well Cast does not conduct heat that well so the handle often never gets too hot (I still slip on an OVE GLOVE though. No sense taking chances)
Make sure a magnet sticks to anything you plan to cook on.
And as I said above, the trick of laying a splatter sheet (Dish towl or paper towel) on the burner before cooking makes clean up much much faster.
