Well, do you want to bring it all together or have a nice accent over the island? Using the coordinating Hubbardton Forge pendants would bring it together and you're all matchy-matchy which is a pretty safe way to go. Using the colorful smaller glass pendants would be a nice accent IMO. I'd go rather small and narrow due to the size of the island and use 2-3 of them depending on the width/diameter of the pendant. Personally, I like the majority of my house to coordinate with special accents here & there like those pendants you & your kids like. And as I had to point out time & time again to different designers & subs--Lots of thought has gone into this decision and while I appreciate your insight/input, I am the one who has to live in the house when it's finished--not you, so please order and install what I have selected.

Hope this helps!

Well said dreamhome! As the homeowner, you have to please yourself. Don't be afraid of telling the lighting designer you are doing your own thing. I love the idea of a pop of color over your island. A relatively painless way to do this is to go with inexpensive mini pendants from one of the box stores. They have lots of colorful shade choices. If you decided you can't live with them,you can always replace them later.
